Okay, You Can't Tell Me These Guy's Aren't Fans of SimEarth

Computer models show the possibility of Earth-type worlds around other stars.

New computer simulations of known extrasolar planetary systems suggest about half of them could harbor an Earth-like world, mathematically speaking.

All of the known planets orbiting other Sun-like stars – there are at least 130 – are very massive, most similar in heft to Jupiter. Earth-sized planets, if any exist, can’t be found with present technology (with the exception of a handful discovered around a dying star). But several models by different groups have shown rocky planets about the size of Earth could exist in known systems where a giant planet orbits a Sun-like star.
