Will there be a earth 2?

Answer 1

A:'Earth 2' would be a second inhabitable world, or planet. There are, of course, seven other planets in our solar system, but none of them is habitable for life forms such as ours, although Mars comes close. In just the last few years, astronomers have discovered numerous other worlds around other stars (or suns), so it is only a matter of time before they find one that is inhabited. Then interest will centre around how similar and how different the life forms of that world are to ours.
