Kepler-62f
__NOTOC__
Kepler-62f〔〔 (also known by its Kepler Object of Interest designation KOI-701.04) is a super-Earth exoplanet (extrasolar planet) orbiting within the habitable zone of Kepler-62, the outermost of five such planets discovered by NASA's Kepler spacecraft. Kepler-62f is located about 1200 light-years (370 parsecs, or roughly 11,350,000,000,000,000 km) from Earth in the constellation of Lyra.〔(Kepler-62f: A Possible Water World )〕 The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler-62f may be a terrestrial or water-dominated solid planet; it lies within the outer part of its host star's habitable zone〔(3 Potentially Habitable 'Super-Earths' Explained (Infographic) )〕 and has an Earth Similarity Index of 0.69.
==Confirmed exoplanet and host star==
Kepler-62f is a super-Earth with a radius 1.4 times that of Earth.〔 The planet orbits a (K-type) star named Kepler-62 that is about a third smaller and cooler than the Sun. The star Kepler -62 is orbited by a total of five transiting planets, of which Kepler-62f has the longest orbital period.〔 The star would appear a slight peach color to the naked eye, and, as viewed from planet Kepler-62f, would have an angular size about 90% as large as the Sun seen from Earth.〔
