Science with Atbin's video: Kepler-69c

Kepler-69c (also known by its Kepler Object of Interest designation KOI-172.02) is a confirmed super-Earth extrasolar planet, about 70% larger than Earth, orbiting a Sun-like G-type star, Kepler-69, located about 2,700 ly (830 pc) from Earth in the constellation of Cygnus. The planet was discovered by NASA's Kepler spacecraft using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler-69c is most likely a terrestrial planet. Initial discovery of the planet was announced on January 7, 2013; confirmation was announced on April 18, 2013. Although it was initially thought to be in the habitable zone, it is now thought to represent a super-Venus, analogous to Venus but more massive, and thus highly unlikely to be habitable.
