Kepler-62f is a super-Earth exoplanet (extrasolar planet) in orbit around the star Kepler-62, the outermost of five such planets discovered by NASA's Kepler spacecraft. It 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 is most likely a terrestrial planet within the outer part of its host star's habitable zone.[1]
Given the planet's age (7 ± 4 billion years), stellar flux (0.41 ± 0.05 times Earth's) and radius (1.41 ± 0.07 times Earth's), a rocky (silicate-iron) composition with the addition of a possibly substantial amount of water is considered plausible.[1] A modeling study accepted in The Astrophysical Journal indicates the planet is likely to be completely covered by ocean.[2]
