Hey everyone! My name is Saturn.
Do you want to impress your friends with some amazing space facts? Well, keep watching.
Our Sun is a small dot!
Wh... What? No way, look how big I am compared to your Earth!
I can fit 1.3 million of your Earth inside me. I think you're wrong Saturn.
Yes but...
Apologize please...
But hang on...
Apologize please...
No hold on...
Hear me out. You are a small dot compared to the largest known star in The Universe.
Oh, but I'm massive. I'm about 1.3 million km s in diameter.
Well this star is about 2.3....
Well that's not much bigger.
,,,billion kilometers in diameter.
How much bigger is that than our Sun?
Well this star, which is called UY Scuti has a radius that is 1700 times bigger than our Sun!
Oh my....
Let's see what our Sun would look like compared to UY Scuti.
Uh, I'm tiny.
UY Scuti is found in the middle of our galaxy, The Milky Way.
Perhaps most amazing of all
If you replaced our Sun with UY Scuti, its surface would stretch past...
Mercury
Venus
Earth
Mars...
and beyond Jupiter! That's massive!
And there are probably bigger stars in the Universe than that, we just haven't found them yet.
Sunsets on Mars are blue!
Hey, I'm Mars and sunsets on me, The Red Planet, are....well blue!
On earth sunsets look yellow, orange and red.
Well, are you sure they are blue?
Yes, take a look at this photo taken from the surface of me, by NASA's Curiosity Rover.
M y atmosphere has fine dust in it and this fine dust scatters red light so that the sky appears
reddish. Which lets blue light through near the sunset. On Earth, it's the other way around.
That looks really cool.
That's not cool! I'll show you cool! Satellite give me a beat!
My name is Mars and my sunsets are so coo l...
Okay, okay Mars. I believe you. Let's hear the rest of the song later.
Hey Mercury, I've got a space joke fo r you.
Oh great, another joke.
What do you get when you cross a lamb and a rocket?
I don't know.
A space sheep! Spaceship, Space Sheep. Get it?
I don't even get paid for this!
Hmm, well anyway. Next time your friends or family want an awesome space fact, tell them sunsets on Mars are blue!
That sheep joke was rubbish!
I know.
Quick Fact! A moon looks like a pizza!
There is a moon in our Solar System that looks like a pizza.
Do you know which moon it is? If you didn't know, the moon that looks like a pizza is IO.
A moon of Jupiter. It looks like this because it is covered in volcanic craters.
Nice pizza can I have a slice?
No, no, it's a moon not a pizza!
Come on, don't keep the pizza all to yourself!
No it's a moon honestly!
Sure. Come on, just a small slice.
Space is silent to humans.
Think of your favorite space movie and you will see exciting chases with loud spacecraft...
...cool sounding lasers and massive explosions!
But this is what it would actually sound like to us in space.
Why is there no sound in space?
Sound travels in waves and through air, water or material.
But it must have something to travel through. There is no atmosphere in space which means that the
sound has no way to travel.
So how do astronauts talk to each other then?
They use radios to talk and on the international space station there is an atmosphere so they can talk normally.
Hey we can hear the rest of my song now. Satellite give me a beat.
My name is Mars and my sunsets are so cool.
Hang on there's no sound in space...
I 'm the coolest planet that you know...
Ah that's better.
Venus spins backwards!
Venus is the only planet in The Solar System that spins backwards compared to the others.
Most planets spin just like earth does here.
Hey Earth.
Hey.
But for some reason, Venus spins like this.
Weird. Go faster please, just to show them.
faster
whoa
Why does Venus spin like that then?
Well scientists have two possible reasons why this might have happened.
Maybe it used to spin the same way as the other planets. Then over time it slowed down to a stop.
Then it started to spin the other way!
Or maybe it does spin the same way as Earth.
Maybe it's just that Venus got turned upside down at some point.
So Venus is the only planet who does this here.
Wait, wait, wait. I also spin in a weird way. I spin on my side.
Let me tell you, I...
That's a story for another day Uranus.
What, but...but..I...uh...
Sorry out of time!
Oh well!
Whoa!
