Kepler Discovers its Smallest Habitable Zone Planets
Pasadena CA (JPL) Apr 23, 2013
NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. The Kepler-62 system has five planets: 62b, 62c, 62d, 62e and 62f. The Kepler-69 system has two planets: 69b and 69c. Kepler-62e, 62f and 69c are the super-Earth-sized planets. Two of the newly discovered planets orbit a star smaller and cool ... read more
