WASP-8b is an extrasolar planet discovered (with their stars) in the SuperWASP batch -6b to -15b. On 1 April 2008, Dr. Don Pollacco of Queen’s University Belfast announced them at the RAS National Astronomy Meeting (NAM 2008).〔(【引用サイトリンク】 url=http://nam2008.qub.ac.uk/press/2008-08-release/ )〕 At 49 parsecs away, this system is the closest of the WASP-discovered systems: closer to Earth than are HD 17156 and HD 149026. It is denser than Jupiter. If it were possible to stand on its surface, one would experience a gravitational pull of approximately g, resulting in difficulty breathing and eventual brain damage. The planet orbits retrograde.〔(【引用サイトリンク】title=Artist’s impression of an exoplanet WASP 8b in a retrograde orbit )〕〔 〕 The equilibrium temperature is 950 K, but this oscillates due to eccentricity.〔Patricio Cubillos ''et al.'', "The Characterization of the Cool and Eccentric Exoplanet WASP-8b with Spitzer" in DPS Annual Meeting session "( 103.Extrasolar Planets: Atmospheric Chemistry and Characterization )" (Monday, Oct 15, 2012, 11:40 AM -11:50 AM).〕 ==See also== * SuperWASP 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「WASP-8b」の詳細全文を読む スポンサード リンク
