Earth-Size Planet Candidates Found in Habitable Zone
2011年2月2日 · Kepler-11, located approximately 2,000 light years from Earth, is the most tightly packed planetary system yet discovered. All six of its confirmed planets have orbits smaller than Venus, and five of the six have orbits smaller than Mercury's.
Kepler-11b - Wikipedia
Kepler-11b is an exoplanet discovered around the star Kepler-11 by the Kepler space telescope, a NASA -led mission to discover Earth-like planets. Kepler-11b is less than about three times as massive and twice as large as Earth, but it has a lower density (≤ 3 g/cm 3), and is thus most likely not of Earth-like composition.
