Kepler Planetary Discovery Live: What did NASA find on its mission to find ‘Earth-size planets’?

National Post | News

NASA has unveiled new planetary results from its Kepler mission, and has found two very Earth-like planets and another which they term a “super Venus.”

“Two of the newly discovered planets orbit a star smaller and cooler than the sun. Kepler-62f is only 40% larger than Earth, making it the exoplanet closest to the size of our planet known in the habitable zone of another star,” NASA explains in a release. “Kepler-62f is likely to have a rocky composition. Kepler-62e, orbits on the inner edge of the habitable zone and is roughly 60% larger than Earth.”

The distant duo are the best candidates for habitable planets that astronomers have found so far, said William Borucki, the chief scientist for NASA’s Kepler telescope.

A planet in another system, Kepler-69, is a slightly less ideal candidate, though only compared to the other two.
