General   (General discussion, talk about anything.)

The Sun is just a star and has 8 planets, one is the Earth, Astronomers believe there are more stars than all the grains of sand on Earth, if some of the stars have planets, it seems obvious that there must be lots of other planets that are similar to Earth. The nearest star to earth though may be 4 light years away, so I can't see us getting any visitors just yet. But.
