__NOTOC__ 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 from Earth in the constellation of Lyra.〔(Kepler-62e: Super-Earth and Possible Water World )〕 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〔(3 Potentially Habitable 'Super-Earths' Explained (Infographic) )〕 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.〔(Super-Earths: Two Earth-like planets that could host life discovered ). ''Indian Express''. 20 April 2013〕 ==Confirmed exoplanet and host star== Kepler-62e is a super-Earth with a radius 1.61 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Kepler-62e」の詳細全文を読む スポンサード リンク
