Solar System || lecture -1 || Parmar ssc 3.0 Geography || Geography

0:08 so hello everyone and good morning everyone co and welcome to the first lecture of the New batch and that is GK batch We are the ones who started 3.0 Geography from and in geography you know we Let's start from the world Geography is fine so that is what we Indians If we study geography, we can understand it properly came to attend the first lecture on World Geography wala hai solar system that is saur mandal good Morning all Once everybody confirms the voice all things are proper No, then let's start today

0:55 You guys must have a lot of doubts in the lecture in the mind of how to do what and how not to do if it has to be done then it is ok if it doesn't happen then I will do a I will bring a separate video on how to do everything things, as many of you might know how to do it but because you Many people have just given their CGL exam would have given And it's okay, a lot of people are expecting that There will be many more people to clear If you are not doing it then what will happen in 2025 Doing some preparation first thing Let me brief you about our batch It is going to remain or whatever our 2025 There are exams not only of SSC but also All of them are around SSC level. We target those exams which are held in So mainly here we will talk about SSC only are targeting but do you know this things don't become that different

1:42 Now you know the Rajasthan CET paper I shared the review with you All the exams are available on Telegram in all almost whatever we do here We cover it, it benefits us equally Whatever your exams are in 2025 Every exam is going to have this target This will save you, you just need to pay attention to this The first thing we have to keep in mind is that our classes Actually it is starting from today, Tuesday But usually it will be Monday to Friday because today was first of october It was the first day so we did it first I started from October, ok Tuesday but by the way monday to friday class You will have a break on Saturday and Sunday on sunday you guys mean okay mock etc. whoever is yours will get it Whatever will be in the application, we will do it from Monday

2:28 We will study this mock exam on Friday How are people going to cover the subject? As usual we are from geography We're going to take a start like we did In the last two batches, we did it in such a way that we People took Geography like first batch I started with politics In the second batch, I started with history. if we did it then it remains like we people Geography is like history After that I took a science subject After this I gave up politics and a science They are going to do the subject in this way It doesn't matter that much, what matters is that which is where I'm going to get you to do things No matter what the subject is, it is There is going to be a hole in you Hole in the Sense that you don't need anything else there might be some book, nothing, now I know you Many of them are hand written notes I am asking about that sir which is hand written First thing is when will we get the notes

3:14 whatever we do here will be in his hands Written notes available on application There will be live classes, you will know everything that live class is streamed here for free I am going to do each and every subject Every lecture of the chapter is available here for free live going to stream and then immediately Enter the application in recorded format It may go away, it may not go to me I don't know exactly, I won't see it So if you guys say it as a demo will be left

4:00 you can take it how can you take it you will know it soon because It takes time to print things like books etc. It takes time to do so then all the notes will be there This will make the notes appear in front of you like You are taking a class and the notes are in front of you. it is already available okay now that notes what is it that anything like those old batch if there are notes of then it is not so In Geography, if I studied the Solar System If you had taught something in your old batch then now And the solar system has completely changed, isn't it? This is the old mindset of people After hearing this, yes definitely we will try new things That's when we will bring a new batch here I have started paying and due to this I have been stuck for one year no batch had come from ok so that is new I will tell you things in a way that it is not So you can add on new things there. You have books like those which are hidden the notes that I am talking about are your The soft copy will be in front of you

4:47 You will get your notes on the application when you People who might have enrolled you There will be a lecture and right next to the lecture Both are different in English and Hindi If you read the notes then they will be updated there okay but if you stay because if you are doing a hard copy then a hard copy If it has already been printed then it will be there But then you might have to update it All those things from your side when books etc. If there is any problem then I will tell you all those things in advance I'll tell you things clearly ok It will be clear that it will be 30 minutes or not 30 minutes It will be 15 to 20 minutes, ok Hindi Hindi I will definitely focus on Hindi medium also. I will do it, it is all right, please give me your feedback I will try to complete it in hindi You will get the notes in proper Hindi. There is no doubt that you will get one of them You will find the word in Hindi which will tell you the work

5:33 I will try that too, wherever Hindi medium students should definitely Any doubt or some query is not resolved We are also going to stay here, just one thing I want to take a promise from you then Also the meaning of commitment is a saying which is famous saying is finishing what you've started or So don't start and finish that thing Make sure you do what you have started many of you here I I am watching, they are starting, okay It is a good thing that many people are taking the start yes today it is ok there are 12000 and more people But the thing is that so many people stay till the end I will not be able to continue, okay at least It is obvious that some people will have some No problems arise in between But if you want to make your GK very strong okay if i want to do it really strong then i will just

6:19 I am asking you for one thing, that is just one once in a while just as many things here as are properly But it's happening, you just keep doing it, okay And then there's more you have to do You won't need it like I said You won't need any books or anything You have the notes, you have the lectures, I have them I will get everything done for you from my side all the things that are important than everything We do not mean that everything here is two my job will be that is to keep things in order brother After refining, you have to give the end which It is important that we do not miss it What kind of people are we? So first of all Theory will do as usual like the old two we did it in batches and after that we All the latest SSC papers that were conducted Whatever questions were asked in it from a particular topic like today we The topic we are going to discuss is the solar system

7:04 The solar system is as big as that topic Questions asked right now are from the most recent till very recent i.e. last you can assume that We are going to do that here in 3 years okay and that's in the quiz format for you It will also be available on the application Let's do it without wasting much time left I know so many people are watching now There will be many doubts and many queries all will be there but I will answer all the queries now I can't entertain and this is it right now No need to send money, super chat is ok Sir please give me a batch in Hindi today Till now I understand only English I understand it in English but I don't remember it yes please please look for any batch separately it won't happen in Hindi this will be fine I will use Hindi terms here. You have the notes as I told you As soon as the book arrives you can order it If he is in front of you then someone will come to you

7:51 Even if there is a problem, that won't happen anyway So I am here for all the things in Hindi terms I am going to use it but if by chance If it comes, it is because the notes are in front of you if they are open then they too are not going to come, this Facility is still available in first and second batch it was not available that the students had they already have those notes it's ok Class is not running on application [music] no need to do youtube4 at all I need to focus on my studies because Right now I'm going to focus more on your comments. I will not do it while teaching so that is why you too Don't focus on super chat, focus on your main studies keep focus, okay whoever has any doubt I I will answer everything but in the last it will be ok If it is not there then some people will say hey sir

8:38 Start quickly, Ram Ram Ram Ram everyone Who says Jai Bajrang Bali, today is Tuesday It's Tuesday, hopefully everyone gets vaccinated You must be sitting there chanting my name after taking a bath well you can say something special which your name is lehi let's start yes geography okay geography means Geography is now the father, mother and aunt of Geography Uncle will not do all this directly through solar system Let's start from where the question arises hits that is solar system what is a solar system so what is a solar system is a bigger part of the universe solar The system will be known to everyone so much a sun it happens and there are planets okay so Everyone must know the basics that sun exists there are planets but it is not as a it's not just a smaller it's a very

9:24 very very very small part of solar off a very very very universe of the universe Our solar system is a very small part System First we will know about the Origin of Universe first understand about it then I will explain it to you I wonder how small a part the solar system is In which our sun and all the planets No matter how little space it occupies Across the Universe in Occupied what is the universe then the entire matter which The universe is making him exist They tell us how the Universe originated First of all, we also call Universe as Cosmus. if we give then that is why the study of this What do we call the study of this? we give

10:10 Cosmology This is what we call cosmology There is also astronomy like this Astronomy is also a thing if you Sometimes you can ask what is astronomy Astronomy is a branch of science that Deals with Selette Bodies Meaning of Selette Bodies which are astronomical objects such as that it's okay it's okay no matter how many suns you have became stars, became asteroids, became comets All these have become matters, we are telling them When we talk about bodies then the study of all these The science related to it is called astronomy they say that means that science that Deals with seletin bodies Cellette

10:56 body space and universe as a whole is Now let's talk about this in Hindi a theory was given about how our The origin of the universe is called What is The Big Bang Theory actually like now This is a show, there is a show on TV in USA on Big Bang Theory but he has nothing to do with it Big Bang Theory has nothing to do with it Was this to be believed or what does this theory say This theory says that this Our universe is already very infighting hot, very dense, and very small one One thing we can say is that there was a lot of infighting

11:44 okay we were listening from the side I sat there and went out and saw the universe Now this universe has been created This is the theory of Big Bang Explosion How did the scientist prove this brother We heard it, but not everyone did. Or is there no one sitting, because this This is a complete explosion, this happened, Raffele you man can 13.8 billion years ago in Hindi 13.8 billion years ago, this explosion happened When it happened, no one was sitting and listening other than us then how did we find out so f It was found out that even today because there was an explosion The explosion that happened is still happening today Our universe is expanding

12:29 And how do we get to know that we It turns out that our seletin bodies are the celestial bodies, the distance between them is increasing Look, infighting is going on It is happening, it was very hot at first, it was small And it was very dense, who had given it This is the first time we know about the whole Big Bang explosion this was given to the concept of When was this given? SSC asks this question There are many years on the list, most of which are from 1931 He did this thing at the time of Big Bang Explosion theory was given and more have come Like a steady state theory has also come up But it is not adopted that much

13:15 steady state theory in hindi It is called the steady state theory. State theory this is the steady state theory who gave this to you? it was given by Fred Hoile Mainly Fred Hoyle and there are two more one of the scientist's name is bundy okay But he won't ask that much, just Fred Hoile Keep in mind that he has maintained steady state He gave a theory and spoke about this theory As per what I told you, the permanent state The theory that the universe is expanding but its average density is The average density is maintained and Its universe is constant Constantly Spending But at the Same Time it is maintaining its average density which is constant ok i am telling you straight away that

14:01 If you get a question from George Le Miter gave the Bug Bang Explosion that kiss A very small particle like this is absolutely explosion happened and this is our different y You are roaming around, do you know what is the galaxy is this galaxy what is it so galaxy That is the whole part which is spiral would have been a part where our stars, sun stars, are planets, all these are there, there are many galaxies There aren't many such things in our Universe right now We have completed the whole universe I read very little part of it properly We have studied the universe, now I will show you How small is our galaxy The Milky Way Galaxy Our Galaxy Meaning where our solar system exists It does, yes, you can understand it like this right here that there is a small part which is called

14:46 What does the Orion Spur say? What does the Orion Spur say? What does the Orion Spur mean in the Orion Spur Do you understand how big the universe is? There's no end to the infighting Friends, there are many galaxies in it caught one of them, the Milky Way Galaxy, which It is ours and it is a very small part of it That's where we're located in Orion, the Solar Where is the system located? Solar system okay now our solar system that is solar How did the system become what it is when I'm talking about What does this mean for the solar system? Meaning that Sun at the Center is still his We will see the photo, you can see it here But first let us understand how it is made

15:33 Solar system then it is believed that again someone So no one sat and saw it except me If we talk about the solar system, its Formation Ruffle 4.6 billion years ago or we are 4.8 Billion years ago I can say ruffle it's okay This program started 4.8 billion years ago Happened Whose house to roam, home to home, this what went from house to house to house This rotating nebula is nebula then it is believed that our solar The system was born out of a nebula The Nebula Was a Cloud of Dust and Gases There was a cloud There was a cloud of dust and gases So what happened is that something like this is believed

16:20 Waves moved due to which the clouds became very strong when it spun it spun very hard it itself but only So because of that gravity you fall on yourself In Kolappan, a thin disc was formed like The disc rotates and spins like a Similarly, all the matter that was in this entire cloud of dust and gases which rotate such as When it started the whole matter came to the center And that created so much pressure on the center

17:05 There was so much pressure that here Hydrogen molecules were those that fuse together you did it and this is what we call it nuclear fusion atom Condensation nuclear fusion is called in Hindi are you nuclear fusion hydrogen so much You might know it or you might not know it, so understand it like this When two nuclei join together they become smaller So a big nucleus is formed here hydrogen nucleus combines to form helium that's why at present when we are in the sun If we look at the composition about you will read that the sun is there and this sun has become right So this is the nuclear fusion in the centre Hydrogen happened because of extreme pressure If it is developed then in between hydrogen Fusion happened and because of that it was formed here sun sun and this thing here like this which

17:54 the matter was rotating it became This planet became a sun at the center and the rest These spirals were like concentric circles I am in concentrated circles, you must know that the circles which have the same center The matter that is rotating and revolving there what was it that slowly condensed and became He became yours If I understand this, then this is the solar planet the system that has the Sun at the center and us moving around her planet right now or which origin nebula right now who gave this theory then this theory is the best It was first proved by Inul Kant that Emmanuel was a German philosopher

18:40 Immanuel Kant wrote this in 1755 She said how the rotating gases etc. which formed our solar system The work of doing individual improvisation in this Kia Lap Less did this and when 1796 that's why it is called Is Nebula Lap Less or Lap Less Theory Nebula understood why it is called lap less Because scientist has done research on this Lap Less and Inul did the improvisation What is the difference between Kant and Kant? It is very minute. There was a difference Inul Kan said that first the Sun was made Then Planet Laplace spoke vice versa that is first plots made and then son but If someone asks you that brother when did our world come into existence what is the age of the earth 4.5 billion years ago you would die okay This question was asked last time in CGL Mains CGL 2023 Mains has been asked now

19:27 In 4.5 so meaning making program started was 4.8 billion years ago 4.5 billion years First, our solar system is formed. sorry our earth etc and all these planets you This way you can understand that you are ready The solar system will obviously go away later Universe existence must have been created first I might have come across it but you should look at the theory Its description of the solar system was given earlier Later came the question of the origin of the universe When is it believed that the universe started forming? goes back 13.8 billion years ago Clearly things are not that simple anymore First tell me if anyone has any doubts even here No, no one even has any doubt

20:18 does anyone have any doubt even here, no doubt The duration of core will tell you everything in the end I am not ok yes sir there other universe still exists So there is no such theory that anyone else The Universe Can Exist The Year of Kant I told you so 1755 It is written here that you are sleeping

21:06 come on it is not that simple that The sun is sitting at the center and around it Our planets are spinning and much more There are all the seletin bodies and many more In our solar system only solar system If you are talking about then now you will understand I realized how small a part the solar system is You can understand this as the whole universe There are many galaxies in that universe Out of that, our Milky Way Galaxy and Sometimes a question is asked that Nearest Galaxy Nearest Galaxy to The Milky Way Galaxy, which is our Our galaxy is the Milky Way Which galaxy is the closest to it? Nearest Galaxy to the Milky Way which galaxy is this adro meda meditation

21:53 it's ok to keep it this is adro meda galaxy It is clear that there are many galaxies among them Our Milky Way Galaxy is very small There is a part called Orions but you can see it in that too are in the solar system because our There are thousands of solar systems in the galaxy itself thousands of solar systems thousands of solar systems in One of them is ours and how many planets are there in it there are eight planets that will take care of us The solar system has a sun at the center what kind of star is this which is the only star It is the only star of our solar system They will say, Sir, we can see the stars they are not stars of our solar system sun at the Centre At The The center is ok and take care of it and that too

22:40 So you will get the point later but right now I I told you that all the matter condensed inside At the center, the whole solar system costs 99 rupees. The month on month 99 is next to the sun Do you understand the whole solar system? We have a month and 99th month is of Sun only is the sun at the center and at planet revolve around it okay it's at You can see the planet here and five duff planets that we know about At last we will read five cards planets move right ahead celestine bodies If we classify it a little bit then

23:25 We know a lot about the solar system and our planet. Let's study Cellulate Bodies in detail in General we can classify them in two parts can a luminous and one okaya no non luminous ok is luminous and non Luminous Luminous means that There are two seletin bodies f have they their own light have they their own The light is their own light There is light for example The stars who are our stars He has his own light, he makes his own light If we talk about non luminous again

24:12 have their own light luminous which do not have there on light we do not have their own Lights that do not have their own light for example like which would have been our asteroids That is, those which we call pure planets. which are our metroids Say it, say it, say Mater or say it, say it, Metroid Things are not the same but are similar to many extents till then what is the difference, we will see it now Those who are called comet Ketu, which is ours the moon is the moon we see the moon glow but his own is fine like

24:59 Our moon is also a non-luminous object So that light is not his own, it is ours We can reflect only the light of the sun If it does then it has its own light then it is not luminous it is non luminous now this whatever is left here I have written the terms brother stars asteroid may meteorite comets meteorite Let me first understand the difference between them Moon, you all must know about it we'll see but I know your There will be a lot of confusion in this stars You know the stars will also see you soon What is Group of Stars and all the things But first, let us understand that esters id meteoride mater meteoride and comet in these what is the difference what is this is this comet what is this this is your comet which In Hindi it is called Dhoomketu or Puchal

25:46 Tara this is what your rock is made of Dust or ice or gas All of this would have been a result of what happens when it comes close to the sun When it comes close to the Sun, its ice etc., dust etc., this rock is melting starts up because of which it has a This kind of tail develops It gets developed, hence it is called tail This star is called a comet, it appears quickly We don't get to see Paldi Neke Dye There is a very famous comet which we call It is called Halley's Comet, this comet which is it means it very rarely looks like this The last time it was seen was in 1986 when you were born

26:32 It would not have happened, obviously it would not have happened I think all of you after 95 It must be from 95 or later I mean people from 99 are from 1980 and some from before that. It must be absolutely fine, since 1986 Well no, he must have been born yet And when will this be seen next time in 2061 I will go and see when maximum of you all people maximum are all old It might have happened or it might have happened No, in this world it is better than you Take it, this is reality, okay, so this is it Halley's Comet is very rare for us to see If you see this, then Halley's Comet is the most famous one It is a comet, you should understand that these big You are looking at the stones, these are what they call that's it asteroid meteorite and Metroid understands what the difference is

27:18 Are See, because things are same with all of us First let me tell you what is ester ide Give ester ide So you can understand asteroids simply like this - they are big Stone The sun is revolving just like the planets as the planets are revolving around Although these are also rotating, but they are spherical You are not in shape now when I tell you to play tambourine When I teach planets, I will tell you there. What are the conditions to be a planet? To all of you or maximum People may have known about Pluto since 2006 there used to be planet one, are you one of them something most people have experienced in their childhood You must have read that just like Pluto, I too have I read that yes, Pluto is a planet, but Then why is Pluto no longer a planet?

28:06 should be of spherical shape which makes your

29:13 A little bit remains, that's what Metroid is They say meteor body now this meteorite when it comes to our meaning Atmosphere means the Earth's atmosphere When you enter it, these lights up one There is a layer in the Earth's atmosphere which we call mezo sphere i.e. you can write the middle circle but by the way When I teach this in Atmosphere, there too If we see this thing then it will burn there and when they get burnt then it becomes like this It seems that if a star breaks and falls then that star It does not break, it is just matter when If the meteorite enters the Earth's atmosphere It becomes matter when it burns then it looks like this It seems that if it is breaking then it breaks

29:58 it is not tatara it is matter this is what we call it They say shooting star shooting star when lots of meteors If he falls suddenly like this then it becomes a matter showers says mcq i have kept it there we will talk about mater shower ok so when i get it done i will do it here add on that thing to the mater shower okay something We get to see such matter showers Now if we look through a telescope, we can see some matter Meteoroids should not burn on our earth surface I fall down and tell them Metroid That is, the meteorite that enters the Earth's atmosphere those which cannot hold water are called meteorites simple okay this is over now we come What does Conseil mean in Contin

30:45 group of star in hindi What do constellations say? Constellation Group of stars this is what you can see Ursa Major Council now SSC The CHSL exam was conducted as per the rules Questions have been asked now, so try to understand a little Carefully Ursa We know the name of Ursa Major by which name The Great Bear from The Great Bear In Hindi we call it Sapta Rishi Saat It is made up of stars, hence Sapta Rishi known by the name of Whatever conson there is, there is one Asterism can be seen ok it's ok to see asterism What is this asterism? Asterism is like this

31:30 Can you understand that there is a pattern? a this is a pattern of stars a pattern of Stars in a group of stars such as this The pattern that you are seeing is called are the big dipper so it asks you this Which constellation is the Big Dipper asterism? If you see it in Ursa Major to see this You will get clear one more like this there is a constellation and that is this w Many of you have this shape Those who have read APYQ will know Those people must have attended the series etc. you will know that this is okay and we are okay so this do you say what do you call this hey how are you piya ok how are you piya

32:19 How are you Piya, he will ask you in this way Which is the consonance that is W shaped? If it happens then this is what happens to you, how are you okay Piya and the brightest star among them that's Shader okay this is our Cygnus or whatever you pronounce it Cygnus, this constellation is cross shaped then C to cross shape C to Cygnus This is how you will remember your cross shaped constellation happens okay and this is your Orion Constellation Orion What shape is it If it is your R glass then it is not R You must know the glass, you must have seen it like this Have you ever seen R glass like this? There is that sand in it, right? There is sand here.

33:05 It is filled with sand so slowly They call it R glass, so this R Which is the shape of glass The constellation is Orion and the most important in it is The brightest star is she's regal brightest star nice brightest star Well which one is it if we talk about brightest ok brightest star Which is one second from y? Wait, I will write it here where is the space here The brightest star which is there is the sun if He will ask you which is the brightest star Since then, the one who is closest to us Brightest

33:50 The star that is nearest to us is nearest which star is this too The brightest is our nearest The sun is fine and the sun is the only star of us Solar System this thing is clear but brightest star in night sky if you ask me in night sky in night sky if you ask then this is it Yours Which one is Sirius? Sirius if he asks you. Nearest Star After Sun Nearest Star to earth after sun nearest star to earth after sun means after the sun if we

34:36 we will talk about the nearest star that is Proxima century ok proxima century is ok clear thing is ok and this is your Orion right here But what is shown is correct and the same pic And Orion who is known as The Hunter R is glass shaped and somewhat It looks in the shape of a hunter, that's why Orin Kalesan is also known as The Hunter. okay the hunter is going to give you a try before you move on cheese and add some more here Then we come to planets and so on which There is a theory about the origin of the solar system The theory that I told you is the most widespread The theory is accepted and other things are also given like that if I talk about a theory, then it

35:22 It is called Planet Simal Hypothesis Planet Simal Planet Simal Hypothesis This hypothesis is given This hypothesis was given to Chamberlin And remember the name Molton Chamberlin in this he will not ask you about the theory in depth because this is not accepted According to them this much is that brother Sun exists Then he used to do something with other stars There was a contact whose influence was Because of this our solar system was created It is not that accepted but keep this in mind Who gave it and when and the reason behind this theory what is your name okay let's go here now So that there is no doubt, please tell us quickly so that we Let's start our own solar system in which

36:07 that first of all we take turns one by one We will see everything first, Sun and us All the planets are fine It seems Bhola has taken the contract of someone I am not able to understand why I wrote this Bhola son, you studied poorly and from whom did you take the contract Tell 12000 people are watching your 12000 Bhola is having a lot of trouble, son Bhola You are not so naïve that you are dependent on someone You have been sent through, tell me who it is that sir chuch batch should i purchase for f cut 25 Look, Abhishek, Abhishek has asked Abhishek, see if he is not for F cut But I think the result of F cut has just come

36:54 Maybe I knew I was just playing something I had read a lot of meanings a while back The students have cleared the Sir F cut Many people also cleared CDS But I am not making this claim myself. I want to know if F is for cut or that because there are some things you need to do extra No doubt, you may have to face a lot of problems It will be of great help, you will also clear it It may be that it has been cleared but I I would not like to claim that at all brother with this you will do it right is it there isn't it we mean if you're next af cat If you are doing this for batch buying then this is for you If you want to do it, you can do it, no problem not a matter of is there any doubt there is galaxy galaxy there is nothing different The Milky Way Galaxy is also called Akash Ganga

37:40 Let's just say the Milky Way Galaxy They call it Akash Ganga, it is not separate Would hey, slow it down a bit, how slow is it What are you teaching about asteroids and matter? there is a difference there is a difference in size I I told you the difference between asteroid and meteorite This happens because the sizes are very big Can be as big as a planet in size Meteroids can be even smaller, what are they they are what they are, they are made of stone Made of stone, metal and all this They do exist but what happens when Ads collided, accept it or do what I told you That was a comet, all its gases came out if it goes then only a small residue is left, then that which are very small pea grains They can be as small as a pea If you don't have an asteroid, it's just the size The difference is just that Metroid becomes more meaningful

38:25 It came into the atmosphere and burned and then it became matter If I don't burn up in Earth's atmosphere And if he strikes in the sense then he Metroid says ok its clear now When we come to Sun we can read a lot of things Sun is the only star is ok at 99 It has the mass of the entire solar system okay 99 on the mass of the solar system Ruffle is made of hydrogen and helium You can see helium remains at 25 to 28 the remaining 2 is for your remaining gases Nitrogen etc. these remain well written what happened at 99 is it ok from here It takes 8 minutes and 30 seconds for the light to come on It takes 8 minutes 30 seconds for the light to light up minute this is what we call it as if it

39:13 we measure them by the closest distance I take light years from you in light years Sometimes he asks whose unit it is So you should not do this thinking about the year The unit is to mark the distance that is to say Light year is now a unit of distance why do we use light years Because light years are very big which we There are distances to measure them It is used to measure what we call light year If we say then this is what is written here 8 minute 30 second this means that the sun and There is a 8 minute and 30 second gap between the two of light minute this much distance this much is the distance between the two i.e. sun and If we talk about light year in between the earth How much is it if we talk in kilometers So do 9.46 * 10 to the power 12 kilometers

40:01 And we have another unit which is called We say parsec, not pascal The pressure is closer than a light year It is a big unit, just keep this in mind The temperature at the surface is 5800 Kelvin and The temperature in 5600 centre is extremely high Now you feel a little bit of sun understand the structure here this photo is Presented by Dreams Time Thank you to Dreams time so understand the structure here First of all it is very important that the most There is an outer layer, it is called corona then move inside the chromosphere and inside The photosphere will grow, you will remember all this there is no need to do anything a little bit is fine all surfaces etc. these three layers are the most Corona chromosphere is important Photosphere Many of you will now It seems that the temperature in the centre is very high It happens more now in comparison to the outer

40:48 I neither saw it nor showed it here you know that the temperature is 5800 Kelvin and At the center, it's 15.7 million Kelvin. Many of you might feel that the temperature of corona will be low and The chromosphere will be larger than the photosphere it's not like that it's not like that here vice Versa True is much more than a photosphere Corona has a temperature and if you sometime ask whether cha is the visible part of the The visible part of the Sun is the photosphere This question is asked many times in railways also. chuka hai cha is the visible part of sun vo the part of the sun that we can see is photosphere okay so corona chromosphere photosphere Remember this order and which one have we just ordered? Mission sent, please tell me in comment.

41:34 Which is India's first mission? India became the fourth country to do so what has been sent here for the sun Mission sent and which mission is that Aditya Elw which launch vehicle did we use and keep this in mind what is this elv Hay Le Grange Now if the point ever asks you that luggage what is a point and how many lagr points are between the sun and the earth then the first The thing is, there is a distance of five lags between the Sun and the Earth points are lagru points those are points where to place a satellite if you do it then it will remain stable because earth and The forces acting in the middle of the sun They become constant there whose Because if we see any satellite there If you place it, it will be placed there very easily can be placed as many times as we have now

42:20 Before this, three countries had placed he has done it on l1 only We haven't done it anywhere else and which one have we launched? We used polar satellite launch here Vehicle PSLV c57 okay let's move on to the planet now Planet like I told you I told you eight majors are fine straight away major eight major and five tambourines which are planets about them or else we can say eight About the Planet and the Five Duff Planets This is our planet, I will read it to you I told you our whole mass is at the Sun Centre It has it and all these meanings surround it all around or we can say the whole Who are revolving around Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune

43:06 ok i don't remember anything wrong I won't miss it all, I'll take the load there's no problem ok let's go then We have understood everything about the Sun Now we understand about the planet We give them to all the planets we have Terrestre divides into parts those are what we call terrestrial planets okay Terrestrial Planets Terrestre Planets and Others Our Jovians are We call these planets the inner planets. I will give you some answers right now, maybe you don't understand it Whatever is coming, you will understand it now These eight planets of ours are one friend Chapa 6 so there are eight planets okay so these eight Out of these first four,

43:51 We are terrest, let us explain it to you now how are you okay so here you are See picture This is Mercury, this is Venus Earth and this is your Mars Jupiter i.e. Brihaspati or Saturn i.e. Saturn, this is Uranus and this is Neptune or Varuna is between these two planets I'm looking between Mars and Jupiter these are something like stones these are also moving around Just like all the plants are rotating, so is this one they are roaming around this is aster ide what is this it is aster ide it is a pure planet it is They say this because there is an asteroid No, there are two or three asteroids, not many If all of them are asteroids then we would have called them this are asteroids We call this complete belt asteroid belt so the first question you should ask is this takes into account which two planets it is between So Mars and Jupiter, that is, Mars and Jupiter

44:38 But this asteroid belt is Acts as an edge a divide as a divide between as a natural Divide between all the eight planets all these The eight planets are divided into parts of four and four. can divide it into four here and four there That means four on its left and four on its right These four on the left are the ones I love It is called terrestre or inner planet These are known as the inner planets And these four that are outside are called exterior They say what is the difference between them, they understand Now these four people inside are Mercury means Mercury Venus means Shukra Earth means Earth Mars i.e. Mangal this rocky material that is made of stone There are metals etc to look at You will find that their surface is solid i.e.

45:23 The surface is solid, it is solid in these You won't get to see many rings The exteriors are smaller Planets are smaller in comparison to them There are very few moose like these two the poor guy doesn't have any moon Mercury Venus Do Not Have Any Moon Zero Now come from the outer planets there are four of them have a lot of moons okay yes rings can be seen in these sir The ring was seen in only one or two Not only Uranus but all other planets have rings Jupiter Saturn Uranus Neptune all have it but we can see saturn from earth are not visible to others, but they are There is no solid surface, there is no solid surface these two are gas full of gas If they are built then you can make any satellite in them You won't be able to land like we didn't The satellite has been landed on the moon, okay Moon is not a planet but a solid surface or

46:10 Then we sent a mission to Venus If we send a mission to Mars, then there Any satellite lands comfortably no problem ok but here you We can never land the satellite Because these are made of gas and these We call them both Ice Giants They say these are the gas giants and these These are ice giants, they are made entirely of ice but overall we call them gaseous Plants call all four as eminence in The size is very big i.e. size S Compare to Interior Or will everyone close their eyes if they understand People will now close their eyes and visualize you will do what I am visualizing for you Is the sun in the center or is it right next to the sun? Keep it on the left, there are eight planets ahead of you the first four times the asteroid was built later I am not taking four names because one by one right now If you do all that, you will remember the names

46:56 also what do you think is special about the first four that he is solid now when he is solid then what what happens in solid that means all things have come together so it became solid now everything if everything matters together If it has come then it must have become smaller Terrestre planets are small and solid Surface is terrestrial are made of rock fine and They have very few moons and are small The whole opposite part of it is yours It will be fine for the exterior i.e. that they are made of gas in very small They have very big rings and they have lots of satellites come now and open it, now we will move forward one by one Read about all the planets The first planet is our Mercury which we call They say Mercury now our Mercury that is

47:42 Mercury is the closest planet sir ji darkness to the gullible Darkness hey bhabhi son how many id's have you created Today Bhola is sitting, he has the contract Bhola, you are given this, you create 1015 IDs today and sit down You will be blocked because you are such a person If he does anything then he will do it with other ID Quickly brother, this is a message And you just have to copy paste it directly Well now we don't give much tension to Bhola They give tension to Mercury, poor Mercury he is thinking that i am such a big planet and He has grown up following Bhola, well Mercury if we talk about mercury then it is the closest planet to the sun okay you can see clearly it is very close and small too everyone is ok it is the small planet Don't think now that Smollett is the closest Because the closest sun has the hottest

48:27 it won't be hot either who is the hottest We will look into it further if you know tell me fastest planet with speed of R to complete revolution at 17200 km Around the Sun in 88 Days 88 days me apna apna The revolution completes our meaning In how much time does it complete a revolution how much time does it take only then we will Happy New Year Let's Do Happy New Year When a full 365 days becomes a year Nor would you have seen any memes that Hair Earth Complete One Revolution Around the Sun and Her People in Earth Celebrating It is New Year, so it is the same that our almost In 365 days we completed one revolution but Mercury's happens in just 88 days

49:14 One gets completed in just 88 days Revolution The rest of the acts also come in Venus There are a few things, I will write them down later But you should focus on the main things first If I didn't want it, I would have known what happened here and there in Maine The things which are the main reason behind her affair They too have lost their attention Venus It is the hottest planet. Why is it the hottest? because it has co2 that is carbon The amount of dioxide is very high in The specialty is that it traps the heat it does co2 well so that's why it is ok Sunlight reaches him more than Venus close but mercury is hotter you can see it Understand that your brother respects you And your friend's both have jobs together Looks like it's okay, your salary is high In comparison with a friend, but I found out that you

49:59 Your friend became richer sooner than you why did you buy the car etc because it is who used to believe in saving even if it was yours The salary is high but he has more savings The curry is the same, even if it is less in Venus There is mercury in comparison but this is a trap if he does too much then it is because of this ok keep one more thing in mind in this I think it is written here or not This has happened, I will tell you something about it in science also I will tell you, but you must be careful here as well. is that in this we see very thick clouds Dense thickets Thick clouds of clouds are visible h2so 4 that is sulfuric acid We get to see huge clouds This is the thing to keep in mind right now on CHSL Question asked, this will not happen in 2024 You asked the question so I am telling you about it last time I told you okay so also known as earth ka twin we call it meaning's twin sister

50:44 We say this because its size and mass it is very similar to which one in meaning so that's why Earth's twin says one of the two Planets in the Solar System Which Rotate around the axis in a clockwise direction Direction There are two planets throughout our solar system which moves clockwise we move in one direction, that is, one is i thank you in hindi like one is clock clockwise and one is anticlockwise in Hindi I call anticlockwise as counterclockwise Do you have complete Hindi notes? If you get the proper then understand it clockwise like this All the planets we have Planet All Planet rotate west east west to east rotate we do this which we call anti clock

51:31 wise we can say accept to except Which are those two planets of two planets One is Venus and the other we will see who it is like this its name is similar to this also but not now further it is the brightest This planet is the brightest planet and the end Again these planets are bright, don't worry there is no light they are non luminous This object reflects only the sun's light The whole solar system is the brightest the brightest in the by the way the brightest in the by the way If we talk about stars, Star in the Night Sky is that serious thing that I told you about I told you it could be seen in the morning and That's why it is called evening with open eyes Is the Morning and Evening Star okay? That is why it is called morning star or

52:16 Then the Evening Star i.e. the Morning Star or Then which planet is called the evening star so it is Venus everyone should close their eyes quickly say venus it is the it is the brightest it is the hottest thick clouds of h2so f Twain Sister of Earth Morning Star and Evening Star rest All rotate counter clockwise This plant and it has a bigger brother, this Both rotate clockwise and the The last thing is in this Venus is it the slowest Rotation Slowest Rotation Meaning of Rotation what is the meaning of rotation We will study this in the next class. The topic will remain ours but for now

53:01 Like our Earth does one rotation in 24 hours Rafi completes it, which means that one day we Which is called when it is complete on your axis When one rotation is completed that means When one completes one revolution on its own axis If it happens then that is what we call rotation If we say rotation in Hindi then its meaning is like this Understand that one day of Venus is the longest It happens in 257 days, do it 257 * 24 hours That's how many hours it takes for Venus to have one of its own Rotation means We have one rotation in one day and 257 days of Venus coincide exactly with Earth Only Planet to Give Support to Life with the the plain atmosphere where we live Planet The Blue Planet because it has We know water is at 70 so it is blue

53:47 planets say ok it has one Natural Satellite Called Moon This means that the moon is the same What is a satellite? What is a satellite? which are around that planet circling around like you might you are circling around someone and someone is putting it around you, then you If you are putting it around someone then you are the planet It happened like a sun and someone felt around you If it is there then it is your satellite, understand it now So the moon is revolving around us So that is our satellite for both of them. What a scene Mercury and Venus have, poor guy I have you I guess they have no Satellite Mercury and Venus are the only planet ok venus are the only planet with

54:35 No Satellite I will write with no or zero, okay Zero satellite, say satellite, say moon it's the same thing okay now as we are so we What do we do, we keep sending satellites These satellites, those satellites exist, right? This Ro is sending Jaxa, Ross is sending Cosmo is being sent to CNES, France space agency is sending csa is sending As for Canada, everybody keeps sending it to me. It is artificial but the moon is the only one which is the natural satellite of moon if If we talk about it, then the moon is a non-luminous object and this is one of the Rotation Its one rotation and revolution time equals then I will tell you something like this Should I tell you that we only need the Moon only one side of

55:24 the moon is Only one side of the moon is visible to us ka is visible and that is roughly you man can rally be on 60 off moon is on 60 The view of the moon that we see is at 40 There is a remaining side that we can sometimes see it is not there and whatever remains is to be we say far side of the moon okay hey far side of the moon okay whoever wants to see the moon It is also called South Pole, India has We have landed our Chandrayaan, that's right. there is Chandrayaan mission and this Chandrayaan mission We have done a soft landing on the far side Of the Moon and India Becomes the First Country to do so who has soft in the far side

56:12 The landing was done on the South Pole of the Moon Why is it there that we have to go only on one side The moon becomes visible and will ask you a question because its what it took in one rotation The time elapsed is equal to one What is the time taken in re Ruffle mount is of 27 days Lebnite that is Lebnitz that is the highest point here okay we will read the rest when When eclipse comes, what about the moon I will mention it again but for now That's all you need to read ok Let's go

56:59 He said, okay, this thing has become clear, only One side of the moon is visible to us at 60 o'clock that remains on the far side of the moon South Pole happens in Chandrayaan 3 mission Just sent it, tell me the name of lander and rover Please tell me the name of the lander quickly Please tell the name of the rover and the name of that point Tell me where we landed Vikram is the lander, our Vikram Sara Bhai Ji In the name of Rover Rover that is Joe Rovin will do ok Wisdom and point which is Shiv Shakti point and the day we landed How do we celebrate Space Day? Please tell me Space The day has just passed in the recent past Tell me quickly when will we celebrate Space Day Let's do it, Shiv Shakti point is right where

57:46 we have landed now let's move on to mars that is Mars is our last interior planet it is called the red planet as we Earth is called the Blue Planet Why is it called the Red Planet? It has very high iron content Iron oxide is found in This iron rich red soil can be seen here It is found in humans, hence it is called Mars. The second smallest planet is the solar system You don't have to remember which one Which is the largest Smallett and the last one When I will do the Samra I will automatically You will remember everything, which is the largest Who is Smollett? It has all the things Two Natural Moose Phobos and D Moss we just saw the meaning of is one the meaning of is one we have what we call the moon and Mars has two, Phobos and Deimus

58:32 Exactly 23rd August Sir Asking Books When The books will land, you will land soon You will be told that it will be okay, it will be PCS This is the same answer which I gave for F cut okay so phobos and d moz there are two natural mass olympus mons olympus which mass isn't it the largest volcano and the Tallest Mountain in the Entire Solar System This solar system is on our mount Rafle 2.5 is two and a half times bigger than Everest times ruffle you its height if i Let me talk about 22 to 26 km mountain How much is Everest 8848 8848 meters its How much is 22 to 26 km rough, that is that its clear is two and half times so this thing It is clear why Mars is called Red Planet It is said that it has two, Phobos and Timos

59:19 And from here to Olympus is like this okay so now let's move on to Jupiter what is between mars and jupiter asteroid belt now this is this asteroid belt in 2013 we had an asteroid named USA had a crush on Pandit Jasraj ji by Pandit Jasraj ji An asteroid was named after it in 2019 I had kept this name in CGL 2022 A similar question was asked in the exam there is an asteroid here Bennu is an asteroid called Bennu. NASA had sent a NASA mission in Osiris Rex is on the asteroid Bennu okay Just be careful about it for a little while now

1:00:05 Jupiter comes, this is the planet that is our The exterior is made of gas They are very big, there are lots of rings If the mouse is fine then Jupiter is the largest The largest planet of the solar system with the shortest rotation means one day its It happens very quickly, how long does it take to 9 an hour and 55 minutes have passed, who knows, it's a day who was getting the biggest and the longest It takes 257 days for Venus to reach Venus there is no need to remember tha third The Brightest Object in the Night Sky Need to remember After Moon and Venus The Great Red Spot is not a giant storm in the solar system exist on this planet Keep in mind that the Great Red Spot is here You will see that it has at least 95 mas Till now things keep increasing and decreasing like this I don't know how many there will be that we will discover

1:00:51 If we take it, then we add it to it There are so many, earlier there were 50, then it became 70 Then in the beginning, first of all four moose were killed Discovered by Galileo Galilea Moon can see those four moons through his telescope It is called the Galilean Moose because Galileo Galileo was the first to discover Are these big moose or the biggest? Have satellites Europa, Ganymede and Callista Kalista was in the news right now because she was here We can see some layers of the ozone layer Found what was discovered by Galileo Gani Maid is the largest moon among them in Not only among the four but the most among these four Ghani Mate is huge in itself All the largest satellites are Jupiter's Overall, the whole solar system is made of guni The Largest Moon or the Largest Natural

1:01:37 Satellite gunny made ok it has an unclear ring around it means there is a ring around it but he is unclear satan ok come to saturn If we talk about Saturn then this is Galileo also discovered this planet it was Galileo who did it discovered tha gala it is the second There is no need to remember the largest right now I will surprise you she is bright and concentrate rings its rings are big It is bright, very shiny and has rings Who discovered it? Galileo I had not discovered it, I discovered it it was discovered by Huygens right his name was Huygens Christian Huygens, I will write my full name here. I christian huygens huygens this who

1:02:23 Christian Huygens is the one who did this you had covered the rings now you have covered the rings You may have seen me there, let me show you again because between the rings There is something else I want to notice You can see the space between the rings You can see some space between the rings Who discovered it by doing this and that? if he asks me if I did it then what Discovery was done by Kasni, it's okay who discovered the space come on brother let's go why no r ho to hu discovered the space between I had discovered these rings Kasani and that is why the USA sent a mission had our Cassini Huygens mission to Satan Satan can float on water because it has less Density than water is the least dense

1:03:09 This would be the density of Saturn's water and there is 1 gram per cubic centimeter That of Saturn is even less than that, which means that it It is believed that if you see the whole planet we will submerge the hypothetical in water if we If you consider this scenario then Saturn is the only The planet that will flourish will sink all others We will go and tell whoever drowns first Which planet will sink first? The first planet that will sink is Earth because it has the highest its density can anyone tell me its density Density means what is its density I will now explain the meaning of this, first Uranus and Let's finish Neptune quickly We come to Uranus which is Arun the third It is the largest again, need to remember it now No, you might remember it is greenish in colour Why greenish color or green blue green It has this type of color because it contains methane

1:03:56 That is what is known as marsh gas There is a CH4 formula, it has a lot of content I find Renus here Discover it It was done by William Herschel 1781 William Herschel noted precisely this keep it they call it ice giant i told you I told you that there are four outer planets Out of that, our Jupiter and Saturn are I call them gas giants Uranus and Neptune We call it the Ice Giant, the Atmosphere of Uranus is composed of hydrogen and Helium Primer But It Also Contains More WATTAM EXTRA HAS COLDEST PLANETARY atmosphere in their solar system rotates clockwise on it's access like venus to Venus has an elder brother called Uranus Such names are kept like this, brothers Isn't it similar sounding then Venus and Uranus has two brothers so here you are the second one

1:04:41 We will write down the planet, which plot it is Venus and Uranus which rotate from East to West Let's do it, okay, that is, the rest clockwise Everything is done anticlockwise, it's ok At least 27 months and one more thing I will tell you here I would like to tell you about Saturn which is the most The largest moon is Saturn's largest The name of the largest moon is Titan What is the name of Titan and it is considered Is it possible to have life on Titan? It is believed that existence may be here goes under water like in titan Do we have volcanoes here? When hot lava comes out from a volcano By the way there is an ice volcano here kind of means underground here perma It is believed that there is a lot of frost water here that is in titan which is the largest

1:05:28 It's okay if life exists here can and it is the largest moon of Saturn and most of all the Moon so far which Saturn has 146 moons which are yet to be determined Now I think whatever we have discovered is good Uranus became clear who discovered it all the things it has 27 moose it is famous moose Miranda Ariel and Uriel So Famous If ever I look at it a little like this Random ask me and the last planet is Neptune is the farthest planet from the Sun It will be cold too, see this is the coldest The temperature was recorded on Uranus And let me tell you one more thing, that Uranus Known as the Rolling Planet This is why it is called a rolling planet because its axis is this its axis But it is tilted more than 90 degrees why is rolling planet called due to it tilts due to how much it tilts

1:06:17 The tilt is greater than 90 degrees so We can roll it like a rolling plot Now what has happened is that at first only seven planets were discovered near us and this It was not known that this Uranus is so why are you titted brother, why so much It is titrated at 90 degrees, our meaning is also titrated is 25 degrees when we read about the meaning I will come in but these are very titted Everyone had their own reasons but the actual The reason given was again given by whom By that he first means that which is supposed to be It was believed that the influence of Saturn was the reason behind this Uranus is stilted but come back Who is our urbane friend? He said that the space in London It was an observatory, brother, where we had our telescope keep it use it just look at it

1:07:04 Here we are telling you a position look at this position you will see something and when When I looked, I saw it and he said this the reason why it has such a tilt and he was right ok so far no one has seen it I had not discovered it, did anyone see it? Then Urban Levrer didn't know How did people use so much brain? These people used to drive it so much that their purpose was fulfilled I don't even have a telescope, but still nothing He predicted that this position But look, there will be one body, Celestis body The same is influencing Uranus getting the access tilted and getting it there I went and found Neptune there and he did fine and later the world is fine Mahesh is fine in the world, he has done it again Later it will be given its meaning

1:07:49 properly discovered it but The position was described by Urbain Le Verrier in 1846 I am trying to remember the names of the scientists There should be blue in color and it is the coldest planet the coldest temperature The record was made in Uranus but in general the way neptune is I'll tell you if I ask you Which is the closest planet to Earth

…
