Jupiter has a moon, Io, that is the most volcanically active moon in the whole solar system.
The surface is covered in hundreds of volcanoes. Their eruptions can spew lava tens of miles up into the air.
We’ve sent spacecrafts to every single planet, including a dwarf planet like Ceres!
Between 1957 and 2015, a spacecraft has flown past or orbited every single planet from Mercury to Pluto.
Mercury is actually shrinking!
The planet has been contracting since it was created 4.5 billion years ago, and it’s only getting smaller.
Winds on Neptune blow at 2,400 km/hour (1491.3 mph).
The fastest recorded wind on earth was 407 kilometers (407.2 mph).
Space suits are expensive! A full NASA space suit can cost between $15-22 million.
That price was quoted in 1974. Today it would be more like $83-122 million. That’s one expensive suit.
Space doesn’t just have black holes. It also has white holes that emit all light and matter.
I have a white hole too, but you don’t hear me bragging about it.
The sun loses about 5 million kilograms per second, only in energy.
Thankfully, it’s big enough to burn for another 4 billion years. So, we have some time.
Venus actually spins in the opposite direction to other planets.
The most popular theory is that Venus was once orbiting the right direction until a planet sized object hit it and knocked Venus 180 degrees on its axis.
The moon is round? No! It’s lemon-shaped.
The tidal tug of Earth’s oceans have distorted the moon’s shape to make it less round than how we seat it.

I serously doubt about that fact (more trees than stars)
There are an estimated 200 billion trillion stars in the observable universe, so by "space" they must mean the Milk Way. Tree count is correct.
New news- Due recent discoveries involving Keplerian decline in the Milky Way's rotation curve, our galaxy's mass has been calculated to be significantly lower than previously thought.
yeah, I called BS as soon as I read that...
" I don't understand it, so it must be a lie! No, I won't do my own research! Fake news!! Fake news!!"
'Merica!
So I guess it's not like earth.
Yeah, I saw that meme, too.
earth-like just means a rock planet aprox. the size of earth
#3 Maybe the galaxy.
#8 Maybe they mean earth-sized.
flat earth much?
FALSE : There are an estimated 100-400 billion stars in the MILKY WAY (only).
