Stars

The sun is a star, but a million earths can fit inside of it (source needed). (R.J)

The star closest to Earth is the Sun. It is 0.000015 light years away from Earth. The next closest star is [|Proxima Centauri] , part of the [|Alpha Centauri] star system. Proxima Centauri is about 4.35 light years away from Earth (39,900,000,000,000 km)

Stars can be obserbed with a telescope from Earth.

Because of the Earth's atmosphere, it is much more effective to send a satellite with telescopic abilities.

Did you know that the sun is only a small star in our universe? When stars die, they explode into a nova, which can turn into a supernova. when they die, they also create white dwarfs and can make black holes. In black holes, the explosion cause massive gravititional pull and pulls everything in, including light. (Nathan Burlis and Daniel Kim)

In comparison to other stars, our Sun is only considered medium-sized. It is approx. halfway through its entire lifetime. 

Stars are so far away that when one dies, it can take many years for us to see it disappear here on Earth. (?) ^The above IS true. This is because light travels a long way away to reach Earth, even though it travels very quickly.
