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.
