NASA’s Kepler Mission Discovers 461 New Planet Candidates


NASA’s Kepler mission Monday announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun’s “habitable zone,” the region in the planetary system where liquid water might exist on the surface of a planet.

One of the four newly identified super Earth-size planet candidates, KOI-172.02, orbits in the habitable zone of a star similar to our sun. The possible planet is approximately 1.5 times the radius of Earth and orbits its host star every 242 days. Additional follow-up analysis will be required to confirm the candidate as a planet.

“There is no better way to kickoff the start of the Kepler extended mission than to discover more possible outposts on the frontier of potentially life bearing worlds,” said Christopher Burke, Kepler scientist at the SETI Institute in Mountain View, Calif., who is leading the analysis.
