Epsilon Tauri b is an extrasolar planet approximately 147 light-years away〔 in the constellation of Taurus. The massive planet was discovered in orbit around star Epsilon Tauri. It orbits the star further out than Earth orbits the Sun. It has moderate eccentricity.〔 The planet orbits one of the four giant stars in the Hyades cluster that is 2.7 times the mass of our Sun, making it the most massive planet-harboring star. This provides evidence that it was an A-type star when it was a main-sequence. The planet is one of those selected by the International Astronomical Union as part of their public process for giving proper names to exoplanets.〔(NameExoWorlds: An IAU Worldwide Contest to Name Exoplanets and their Host Stars ). IAU.org. 9 July 2014〕〔(NameExoWorlds ).〕 The process involves public nomination and voting for the new name, and the IAU plans to announce the new name in mid-November 2015.〔(NameExoWorlds ).〕 == See also == * 4 Ursae Majoris b * Epsilon Eridani b * Epsilon Reticuli Ab 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「Epsilon Tauri b」の詳細全文を読む スポンサード リンク
