Planets similar to Earth?

Question

I read someones answer to my question earlier and it mentioned a planet 100's of light years away that has the same properties of Earth. Does anyone know where I can read more about this as it sounds interesting.

Answer 1

I don't know about the 100's of light years away but a planet like the one your talking about could be Gliese 581c 20.5 light-years away.

Answer 5

I don't think even NASA know that 100's of light years away there is a planet similar to earth.

Answer 6

Gliese 581c is probably the best "Earth" candidate so far, although it has been argued that the planet may well have a runaway greenhouse effect, like Venus.
