Kepler-438b

Kepler-438b (also known by its Kepler Object of Interest designation KOI-3284.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting on the inner edge of the habitable zone of the red dwarf as it receives 1.4 times our solar flex. Kepler-438b is about 470 light-years (145 parsecs, or nearly 4.5×1015 km) from Earth in the constellation Lyra. 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. NASA announced the confirmation of the exoplanet on 6 January 2015. Although it is not habitable, as of June 2015, it has the highest index on the Earth Similarity Index, with a rating of 0.88.
