share any Interesting fact you know about Astronomy & Space .I will start off with these 10 interesting facts
1.The Sun is so big that 106 Earths could fit across its diameter and 1,300,000 Earths could fit inside of it.
2.Certain parts of space where 'dark matter' is predominate it is about 1/2 degree above absolute zero.
3.Lightning is about 3 times hotter than our Sun
4.Sunspots are areas on the surface of the Sun that are 3000 degrees cooler than other areas.
5.There is a star, called Betelgeuse, that is 450,000,000 miles in diameter, and the Sun is just a dot compared to it. Now that's really big.
6.Did you know that the Sun actually rotates on an axis, well it does.It takes the Sun 25 days to turn on its axis.
7.Comets are made mostly of frozen gases
8.Saturn's moon Titan has hundreds of times more oil and natural gas than all the known reserves on Earth.
9.A neutron star is the strongest magnet in the universe.
10.Imagine the Sun was massive enough to become a black hole (it isn’t, but let’s pretend for now that it is). Would the Earth go tumbling in, never to be seen again? Actually, it wouldn’t. It would continue to orbit the black hole alongside the other planets. This is because orbit is determined by distance and mass, not size. As it happens, the Sun can’t collapse into a black hole, and has a few billion years of life left.
