Kepler-22b

Kepler-22b is a "super-Earth" with a radius approximately 2.4 times that of Earth. Its exact mass and composition are unknown, so it could be either a rocky world or an ocean planet with a thick atmosphere (a mini-Neptune). It lies in the habitable zone, where temperatures allow liquid water to exist.
