Kepler-62e, 62f and 69c: Earth-like planets that could host life discovered by NASA
April 25th, 2013
NASAs Kepler Mission has found five planets orbiting a
Sun-like star called Kepler-62. Four of these planets are so-called
super-Earths, larger than our own planet, but smaller than even the
smallest ice giant planet in our Solar System.The Kepler-62 system has five planets:
- 62b
- 62c
- 62d
- 62e
- 62f
- Kepler-62f is only 40% larger than Earth, making it the exo-planet closest to the size of our planet known in the habitable zone of another star. Kepler-62f is likely to have a rocky composition. There’s also the possibility of water.
- Kepler-62e orbits on the inner edge of the habitable zone and is roughly 60% larger than Earth. Could be either rocky or a water world.
- Kepler-69c is 70% larger than the size of Earth, and orbits in the habitable zone of a star similar to our sun. Astronomers are uncertain about the composition of Kepler-69c, but its orbit of 242 days around a sun-like star resembles that of our neighboring planet Venus. Described as potentially a “Super Venus,” situated on the hotter side of the habitable zone.
