Kepler-62f, a super-Earth, has a radius 1.4 times that of Earth. The planet orbits a star that is slightly smaller and cooler than the Sun, named Kepler-62, which 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.
Given the planet's age (7 ± 4 billion years), irradiance (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. A modeling study accepted in The Astrophysical Journal indicates it is likely that a great majority of planets in its size range are completely covered by ocean (possibly frozen, if Kepler-62f is indeed such a planet). If its density is the same as Earth's, its mass would be 1.413 or 2.80 times Earth's.
