Discovered by planetary-transit methods by the Kepler space telescope in February 2013, it has a radius of 2.31 ± 0.07 that of Earth and a density of 2.46–4.3 g/cm3. It has an orbital period of 5.398763 days at a distance of about 0.0617 AU from its star. Doppler measurements were made to determine its mass to be 5.79 times that of Earth (0.026 MJ).〔http://astro.berkeley.edu/~gmarcy/22kois.pdf〕 With a density of 2.6 g/cm3 it has physical characteristics of both a super-Earth and a mini-Neptune.〔( Masses, radii, and orbits of small Kepler planets: the transition from gaseous to rocky planets ) accessdate=8 January 2014〕 ==See also== *List of planets discovered by the Kepler spacecraft 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-68b」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
