Which Planet Is the Biggest in Our Solar System? (Ultra Compilation)

A playful planet-personification video where the Sun, Earth, Moon, Venus, Mars and others banter about size, rotation, moons, asteroids and rings, mixing real astronomy facts with humor.

Key Takeaways

Planets have very different sizes, rotation speeds and atmospheres
Earth's magnetic field and atmosphere are key to its habitability
The Sun's magnetic activity cycles roughly every 11 years and affects space weather
The video blends accurate astronomy with humor and frequent engagement prompts

What the video covers

Planets are personified and bicker about their sizes, e.g. how many Earths would fit inside Jupiter (about 1,300) and the Sun (about 1,000 Earths per Earth-Sun volume comparison in the video)
Venus is highlighted for its extremely slow rotation (about 243 Earth days) and reversed spin
The Moon's footprints left by Apollo astronauts are described as lasting millions of years due to no wind or water
Earth and Mars are compared: Mars has a weak magnetic field and thin atmosphere, and would be colder if swapped into Earth's orbit
The Sun's magnetic pole flip every ~11 years and resulting solar flares are explained
An asteroid threat to Earth and a comet mistaken for an alien are discussed as harmless or passing by
Black holes 'sleeping' when not feeding is used as a comedic segment
The solar system orbits the galactic center at roughly 220 km/s
Pluto is portrayed sadly as the smallest and farthest planet
The video ends in a playful sequence of trivia and calls to like and subscribe

Chapters

How many Earths would fit inside Jupiter according to the video?

The video says about 1,300 Earths would be needed to fill Jupiter. This is a rough volume comparison that matches commonly cited astronomy figures.

Why does the video say Venus spins so slowly?

Venus takes about 243 Earth days to complete one rotation, and it spins in the reverse direction compared with most planets. The video presents this as a playful joke about Venus being 'stylish'.

What does the video say happens during the Sun's magnetic pole flip?

Every 11 years the Sun's magnetic poles switch places, which makes its magnetic field messy. The video says this leads to more solar flares and stronger solar storms.

Speaker A

Hey, planets, how big are you? If the Sun is talking about size, it's time to run away. Haha, that watermelon seed wants to escape. I can't even imagine how many of me it would take to fit inside the Sun. Just to fit inside Jupiter, how many of me would it take? Guys, do you know? If you know, smash the like and subscribe button.

Speaker A

I'm a small planet. I'll just sit and listen. Haha. Just to fit inside me, you'd need 1,300 Earths. So, you're really small, Earth.

Speaker A

And you, how many of you would it take to fit inside the Sun? To fit inside the Sun, I'd need 1,000 of me. And what about fitting inside me?

Speaker A

Hey Sun, I want to have two moons. Are you sure about your choice, Earth?

Speaker A

That is very dangerous for you. Of course I'm sure. Guys, do you want me to have more than one moon or not?

Speaker A

Listen, Earth. If you have more than one moon, your ocean tides will be unstable, and your people will struggle to survive. And the worst thing is... What is it?

Speaker A

Venus, why do you spin so slowly? It takes you 243 days just to make one rotation. Chill, I'm stylish. I spin slowly so I don't get roasted like you.

Speaker A

Roasted but fast, unlike you. Head down, feet up. Guys, stop arguing. Venus' rotation is reversed and slower than its revolution.

Speaker A

See, even Earth's on my side. Yeah, but Earth also needs 24 hours just to change outfits.

Speaker A

Guys, who's the slowest? Me, Venus, or Mercury? Comment below. Guys, why are you all in such a hurry?

Speaker A

Yo, Moon, what's that mark on your face? This? A footprint. Humans from Earth left it here.

Speaker A

No way. They really stepped on you? Lucky. I'm still waiting for my turn. Yeah, but here's the crazy part. This footprint is going to stay for millions of years.

Speaker A

Millions? Why? Because there's no wind or water up there. Nothing can erase it. Imagine your footprint lasting millions of years. Guys, who wants to step on the Moon? Hit subscribe.

Speaker A

One footprint already lasts forever. Guys, today I'm taking a day off, okay? See you.

Speaker A

Bro, without the Sun, I can't even see where I'm supposed to orbit. Venus, move. Oh, no. What do we do, guys? The Sun's taking a day off. Come on, let's make a hashtag: bring Sun back.

Speaker A

Bro, I haven't even really gotten proper inhabitants yet, and now the Sun wants a day off.

Speaker A

This is my job application to become the new Sun. The Sun's day off means my rings won't be visible anymore.

Speaker A

Guys, what's going on? Why is it so noisy in here? Moon, why are you always gray? Try being like me, blue and green, fresh.

Speaker A

Gray is elegant, Earth, minimalist. You're the one who looks like a messy painting. Messy but alive. You look like an unedited photo.

Speaker A

Have an atmosphere, okay? No color effects, everything is raw. She's right. My light hitting her surface makes her look grayish white.

Speaker A

So, are you glowing because of me or because of the Sun? I glow because I'm her, obviously.

Speaker A

Guys, is the Moon elegant or just plain? Comment below. Hey Earth, Mars, if you two swapped orbits, what would happen?

Speaker A

Finally, I'm in Earth's spot, closer to the Sun. My polar ice is melting, and I actually have a bit of liquid water now.

Speaker A

And I'm the one farther away. I only get about 40% of my usual sunlight.

Speaker A

Temperatures drop, and a lot of my oceans start to freeze. Okay, but what about my solar flares?

Speaker A

I'm still pretty safe. My strong magnetic field can shield most of your nasty radiation. Oh god, I'm not ready for this. My magnetic field is weak. My atmosphere is thin. Your solar flares can strip even more of it away. So,

Speaker A

choose now. Team Earth or team Mars? Comment your team and hit like and subscribe. Oh, no. An asteroid is coming my way in 2029.

Speaker A

Relax, Earth. I'll just pull that thing away with my gravity. Easy. Bro, just evacuate your humans to me right now.

Speaker A

Guys, what should we do? Give me five things you'd do if the asteroid actually hit me. And don't forget to subscribe.

Speaker A

Why are you doing a subscriber promo during a literal extinction event? Chill, Earth. It's only passing by. It's not going to hit you. Thank goodness.

Speaker A

Oopsie. Hey Sun, is it true that black holes can sleep? Yeah, it's true. But not the kind of sleep like Uranus, who just lies there all day doing nothing.

Speaker A

Bro, why me? So, what does sleeping mean then? It means the black hole isn't eating.

Speaker A

There's no gas, no stars, nothing nearby for it to swallow. So, it just looks quiet, like it's in standby mode.

Speaker A

Guys, don't hit the like button too hard, okay? I don't want the black hole waking up. Who's making that noise?

Speaker A

Hey Earth, bad news. The Sun is freaking out. Freaking out? He's totally out of control right now. Wait a minute. Who are you? Nobody can control the Sun. Hey Sun, relax. What's going on with you?

Speaker A

I'm not raging. I'm entering my magnetic pole flip phase. Your what? Every 11 years, my magnetic poles switch places.

Speaker A

And when that happens, my magnetic field gets super messy. That's when I shoot more solar flares and even stronger solar storms.

Speaker A

Guys, hit the like button so the Sun chills a bit. Maybe the storms won't go too crazy. So, you want me to chill?

Speaker A

[Music] Earth, an asteroid is going to hit me. I'm really scared. You don't need to be scared, Moon.

Speaker A

Besides, you don't have humans like I do. If I get hit, a lot of debris will fly toward you. Wait a minute.

Speaker A

If you become debris, that means I'll finally have a ring. That doesn't sound too bad.

Speaker A

Guys, are you team save the Moon or team Earth gets a ring? Don't worry, Moon.

Speaker A

I'll deflect the asteroid so it won't hit you. Thank you, Earth. Okay. Hey Sun, I've got a question. Are you actually just chilling in the center or are you moving and taking all of us along?

Speaker A

Chilling? Hell no. We are all flooring it right now, orbiting the galactic center. Seriously? I thought you were just lounging around being hot over here.

Speaker A

Lounging? Our speed is 220 km per second, bro. That's faster than every single F1 car put together. Wait. So, are we planets or passengers on an intergalactic bus?

Speaker A

So, which direction are we headed? I am the safest planet in the entire solar system.

Speaker A

Hold on a sec. Are you sure about that? Of course. Look at me. I have an atmosphere, a magnetic field, and my humans are chilling safely here.

Speaker A

Bro, your safety is literally because I'm acting as a giant gravity shield. Shield? I'm totally fine on my own.

Speaker A

Guys, we'd be completely okay without Jupiter, right? All right then. See you around. [Applause] Sun, is it true there's an alien coming toward me? I'm freaking out.

Speaker A

Alien what, Earth? People say this object is actually an alien, and it's real. That's not an alien, Earth. Yeah, it came from another galaxy, but it's literally just a comet. But what if it's an alien disguised as a comet? Guys, if

Speaker A

real aliens come to Earth, what's the first thing you all would do? Comment below. Even if a comet looks like an alien spaceship, it's literally just a giant chunk of ice, totally harmless.

Speaker A

Hey Pluto, hold on tight. I can't take it anymore, Neptune. Goodbye. No. Why am I always the smallest and the farthest? Why can't I feel the warmth of the Sun? Why? Don't be sad, Pluto. We'll be here with you in the dark and cold

Speaker A

edges of the universe. Guys, you'll always remember me, right? Hey Earth, have you ever seen an alien?

Speaker A

Alien? I have aliens right here. They're able to survive in temperatures between minus 272°C and 150°C. Wow, they must be really tough.

Speaker A

Of course. They can live for decades without water. Then send those aliens to me so I can have inhabitants, too. Guys, do you agree if the Moon had inhabitants like me? Hey planets, let's have a battle.

Speaker A

First round, who's the hottest planet? I'm the closest to the Sun, so obviously I'm the hottest. Haha.

Speaker A

Don't be so sure, Mercury. Who's got the right answer? Hit like and subscribe. Next round, who's the coldest planet? I'm the farthest from the Sun, so of course I'm the coldest.

Speaker A

Uranus doesn't even try, just sleeps and still wins. Enough talking, Earth. Do you really think you can win against us in this planet battle? Ha, then tell me, who among you actually has life?

Speaker A

Finally, I'm at the closest point to the Sun. Do I get to be a p

Speaker A

Finally, I'm at the closest point to the sun. Do I get to be a planet again now?

Speaker A

Yay, you finally get to be a planet again Pluto. A planet? Try comparing yourself to my moons. You're still much smaller.

Speaker A

Guys, are you on team Pluto should be a planet again or not? But I still orbit the sun. Is this all for nothing?

Speaker A

Listen, to be a planet, you don't just orbit the sun. You also need to clear your orbit of other space objects. Try clearing that one cute little asteroid.

Speaker A

Hey Earth, why do you look so sad? I was just remembering my dinosaur collection, Sun.

Speaker A

Don't be sad, Earth. Now you have so many Earthlings, and I think they love you very much.

Speaker A

Is it true that you guys love me? If your Earthlings don't love you, just throw them over here, Earth. Guys, you know the name of the asteroid that wiped out the dinosaur? Hey, Moon. Look at my new blanket.

Speaker A

Wow, where did you get that blanket from? It's the satellites that Earthlings launched. Guys, do you like my blanket? Yeah, woo. Excuse me.

Speaker A

NO, GOD, PLEASE, NO. NO. GUYS, I only have 22 galactic years left to live.

Speaker A

Hey, don't say things like that, Sun. My Earthlings haven't even moved to Mars yet.

Speaker A

Woah, if you die, what will happen to all of us, Sun? Relax. You'll all be adopted by him.

Speaker A

Guys, next month I'm going to let out a big fart. Yeah, yeah. You said that yesterday, too. But this one's different. It's the peak ultra big fart.

Speaker A

Maybe what the Sun means is this time the fart comes with phlegm. What? Woah, I can't believe this. Guys, hit the like button to show the Earthlings are still alive. Guys, next month I'm totally glowing these days. The other

Speaker A

planets must be so jealous. Speaking of glowing, check out who's got the fanciest ring in the galaxy. Huh? A ring? Where did you even get that? Guys, how did Saturn get a ring like that? I want one, too. Saturn, just a rookie.

Speaker A

Oh, no, it's the final boss. No, someone took my ring. Hey, Earth. Why did you take Saturn's ring? I also want to have a ring like Saturn. Is that wrong? If you want a ring like mine, let me give you a ring

Speaker A

that really fits you. What kind of ring is this, guys? Anyone know? What do you want to be when you grow up, Earth? Hmm, I think I want to be a planet full of cute little creatures, like dinosaurs,

Speaker A

maybe. Uh, that sounds more scary than cute. Hello. What are you two talking about?

Speaker A

Woah, what just happened? Why did you guys crash into each other? What's going on, guys? Hey, Sun. If a black hole can merge into one, can a white hole do that too?

Speaker A

Hmm, that's a tough question. We know a black hole absorbs everything, and a white hole is the theoretical time reversal of a black hole, meaning nothing can enter it.

Speaker A

Guys, are you team black hole or team white hole? Hit like and comment. It's because a white hole constantly emits matter, and since not a single bit of matter can enter it, it's likely impossible for white holes to merge.

Speaker A

What if, instead of merging when they get close, the white holes just destabilize and burst into many pieces?

Speaker A

Hey, planets. Who among you is the most popular? Why even bother with the question? The answer is obviously me. Haha. Just look at these rings. They're dazzling.

Speaker A

Sure, I'm not a planet anymore, but I'm still popular, right, guys? You still remember me, don't you? Like and subscribe if you do.

Speaker A

You forget, Saturn, that my residents are the ones who decide who's popular and who isn't. Try being popular without them.

Speaker A

Oh, don't get it twisted, Earth. The ones who vote me the most popular planet are them.

Speaker A

Earthlings, I got three planets here that are kind of similar, but one's totally different. Can you guess which one's the oddball? Venus and Mars both have thick atmospheres, but their stuff inside, totally different, dude. Mars and I have solid surfaces you can walk

Speaker A

on, but Venus, it's crazy hot with clouds full of sulfuric acid. No umbrellas allowed. Guys, before you answer, if you're a girl, hit like and subscribe. If you're a boy, hit like and comment. The answer is Venus, the hot

Speaker A

one with sulfuric acid clouds that make its sky totally unfriendly. How big the universe really is?

Speaker A

So, you can analogize the galaxies as raisins in a loaf of bread being baked.

Speaker A

Bread? Anyone here like bread? The dough gets bigger and bigger, and the raisins that were close together get farther apart. So, we can't measure the size of the universe because it keeps getting bigger? That's the way it is. But if the

Speaker A

universe stops expanding, what will happen? Hey, planets. What would happen if I farted? Oh, God, is this the reason I don't have an atmosphere? Do I really have to be this close? This is dangerous, guys. Do you think you can

Speaker A

survive this? Maybe this is the time your people move here, Earth. Guys, do you want to move to Mars? Hit like and subscribe if you do. That just tickles us. Haha. As always, doesn't affect me at all. If you think Earth will explode

Speaker A

when it enters a black hole and turn into spaghetti, you're totally wrong. Dude, stop it.

Speaker A

From your perspective as a viewer who doesn't live on Earth, you would see Earth approaching the event horizon of the black hole, not speeding up, but actually slowing down. And as it reaches the event horizon, Earth wouldn't change

Speaker A

shape at all. It would simply freeze in place and disappear. Guys, why is it like this? Does anyone know? Hey, Earth.

Speaker A

Do you know about planet called super Earth? Huh, a super Earth? Yeah, I've heard of it. I am the super Earth.

Speaker A

Not like that, Earth. A super Earth is an exoplanet that's similar to you, but much bigger in size.

Speaker A

Wait, there's something like that, guys? Anyone living on a super Earth, hit the like button. Mars, I'm going to send my people to your place. What for? So, you'll finally have some residents, too.

Speaker A

To everyone who wants to move and live on Mars, hit the like button, guys. Just so you know, my atmosphere is 95% carbon dioxide, a dash of nitrogen, a sprinkle of argon, and barely any oxygen. Good luck breathing here, buddy.

Speaker A

Hey, planets. Where do your names come from? Yo, Venus, your name turns out to be a girl's name. It's not just your rotation that's reversed, but your name, too.

Speaker A

Haha. Hey, Earth. Don't you know where your name comes from? I don't know, Mars. All I know is that I'm home to my people. Guys, do you know where my name comes from? Hit like and subscribe if you do. Hey, Jupiter. Can't you stop

Speaker A

those lightning bolts? Haha. How dare you order a king like me? Your name is just from the god of agriculture. Go mow the lawn.

Speaker A

I'm your father. Look, my children and grandchildren are playing. Playing? Hey, planets. Who's the richest among you?

Speaker A

All you have is iron ore, Mercury? Look at yourself. All you have is poisonous gas.

Speaker A

Wow, you have everything in the universe Earth. Of course, Jupy. Look how complete I am.

Speaker A

Guys, hit like and subscribe if you're my most valuable treasure. Don't you like diamonds, Earth? I have lots of diamonds, and they're falling from the sky. Wow, if I could take all those diamonds, I could be the richest planet.

Speaker A

What would you trade them for? Um, would this work? Hey, Earth. Look, there's money flying through space.

Speaker A

How did you know I needed money? Because you're greedy. Is this a new asteroid? Looks like it's a planet that failed to form. I will launch a mission there right away. Guys, hit the subscribe button so our rocket

Speaker A

can reach it by 2029, and you'll all become billionaires. Guys, I think I'm getting older. Oh, no, please, don't say that, Sun. We're always here with you. I can't hold on much longer, guys. Please take good care of yourselves.

Speaker A

Guys, what if we lose the Sun? WHAT WILL HAPPEN TO US? I'm hungry. Don't eat me, Earth.

Speaker A

If I wasn't here, what would happen? I would freeze. Bye-bye, Earth. Don't go, Jupiter. Anyone know what happens if Earth is without humans? Press like button if you know. Hey, look at my new ring.

Speaker A

Ring? Which one? Open your eyes. Wait a minute. Have you seen Jupiter's ring, guys? Isn't my ring nice?
