翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Octans ： ウィキペディア英語版 Octans Octans is a faint constellation located in the deep southern sky. Its name is Latin for the eighth part of a circle, but it is named after the octant, a navigational instrument. The constellation was devised by French astronomer Nicolas Louis de Lacaille in 1752, and it remains one of the 88 modern constellations. ==History and mythology== Octans was one of 14 constellations created by Nicolas Louis de Lacaille during his expedition to the Cape of Good Hope, and was originally named "l’Octans de Reflexion", French for “the reflecting octant”. It was part of his catalogue of the southern sky, the ''Coelum Australe Stelliferum'', which was published posthumously in 1763. In Europe, it became more widely known as "Octans Hadleianus", in honor of English mathematician John Hadley, who invented the octant in 1730. There is no real mythology related to Octans, partially due to its faintness and relative recentness, but mostly because of its extreme southerly latitude. 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「Octans」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.
