Kepler-62e






Kepler-62e is a super-Earth exoplanet (extrasolar planet) discovered orbiting within the habitable zone of 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.[1] 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[2][3] 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.[2] 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.[4][5]

Kepler-62e orbits its host star every 122 days and is roughly 60 percent larger than Earth.[6]

Confirmed exoplanet and host star

Kepler-62e is a super-Earth with a radius 1.61 times that of Earth.[2] 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.[2] The star would appear a slight peach color to the naked eye.[2]

Cultural impact

On 9 May 2013, a congressional hearing by two U.S. House of Representatives subcommittees discussed "Exoplanet Discoveries: Have We Found Other Earths?," prompted by the discovery of exoplanet Kepler-62f, along with Kepler-62e and Kepler-69c. A related special issue of the journal Science, published earlier, described the discovery of the exoplanets.[8] Kepler-62f and the other Kepler-62 exoplanets are being specially targeted as part of the SETI search programs.[9]
