Kepler-22b is the first planet discovered by space telescope Kepler that orbits a star in its habitable zone. The planet is a super-Earth, 2.4 times more massive than the Earth. It orbits its host star in the middle of the habitable zone, making it an excellent planet to potentially host life. Unfortunately we still do not know if the planet has a rocky, gaseous or liquid composition. The artist's impression below shows one possibility: a planet mostly covered with water with a cloudy atmosphere.
