1.The Earth is the fifth largest planet, and yet, could fit into the sun 1.3 million times.
2.On the other hand, the largest known star, UY Scuti, is more than 1,708 times the size of the sun.
3.The Milky Way is so big that even at the speed of light, it would take 100,000 years to travel across it.
4.And yet, the biggest galaxy, IC 1101, is over 50 times bigger than our own Milky Way.
5.There are over 2 trillion galaxies in the universe...
6....but the planets, the sun, and all the galaxies only make up 5% of the universe. Another 27% of the universe is made up of dark matter, and the remaining 68% is made up of dark energy that the scientists don't know much about.
11.One of Jupiter's storms, the Great Red Spot, is so big that the entire Earth could fit into it.
12.The Great Red Spot is getting taller as it shrinks.
13.There are giant clouds of alcohol floating in space.
14.The distance to the moon from the Earth is 384,400 km, and you could fit all the planets of our system in there, with room to spare.
15.The Earth is about 4.5 billion years old, but that’s only a third of the age of the universe, which is 13.5 billion years old.
16.There is an earth-sized diamond in space, 900 light years away from us.
17.A day on Venus lasts longer than a year on Venus.
18.Even though Mercury is the planet nearest to the Sun, Venus is actually the hottest, because Venus has an extremely dense carbon-dioxide atmosphere.
19.There's a planet where it rains glass, sideways.
20.You can't really cry in space, because without gravity, tears don't flow downwards out of the eye.
21.And, regardless of whether a galaxy is big or small, they all rotate once every billion years.
