Kepler-62e is a super-Earth exoplanet (extrasolar planet) discovered in orbit around the star Kepler-62, the second outermost of five such planets discovered by NASA's Kepler spacecraft. Kepler-62e is located about 1,200 ly (370 pc) from Earth in the constellation of Lyra. The exoplanet was found using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler-62e may be a terrestrial or water-ice-dominated solid planet; it lies in the inner part of its host star's habitable zone and has an Earth Similarity Index of 0.83.
Given the planet's age (7 ± 4 billion years), stellar flux (1.2 ± 0.2 times Earth's) and radius (1.61 ± 0.05 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 suggests it is likely that a great majority of planets in Kepler-62e's size range are completely covered by ocean.
Kepler-62e orbits its host star every 122 days and is roughly 60 percent larger than Earth.
