(The first exoplanet discovery was made by Aleksander Wolszczan in 1992, around pulsar PSR 1257.) It is the prototype for a class of planets called hot Jupiters. == Name == The name ''51 Pegasi b'' is the official astronomical name of the planet. As with all extrasolar planets, the 'b' is used to indicate that this planet was the first discovered orbiting its parent star. Further undiscovered planets of 51 Pegasi would be designated c, d, e, f, and so on. All extrasolar planets have lowercase letters to differentiate from companion stars in the system (which are designated with an uppercase letter). 51 Pegasi b is sometimes unofficially referred to as "Bellerophon".〔http://jumk.de/astronomie/exoplanets/51-pegasi.shtml〕 This name comes from the Greek hero Bellerophon, who tamed Pegasus (the Winged Horse). This refers to the planet's constellation, Pegasus. This name is usually used as the informal name to show the similarities to the planets of the Solar System. The same argument and association with the constellation of host star was used to suggest informal names for other extrasolar planets. The planet and its host star is one of the planetary systems selected by the International Astronomical Union as part of their public process for giving proper names to exoplanets and their host star (where no proper name already exists).〔(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 names, and the IAU plans to announce the new names in mid-November 2015.〔(NameExoWorlds ).〕 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「51 Pegasi b」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.
