NGC 1 is a spiral galaxy SbbPa Ring located 190 million light-years away in the constellation Pegasus. At about 90,000 light-years in diameter, it is just a little smaller than our galaxy, the Milky Way. It is the first object listed in the New General Catalogue.〔(【引用サイトリンク】 work=Results for NGC 0001 )〕 In the coordinates used at the time of the catalog's compilation (epoch 1860), this object had the lowest right ascension of all the objects in the catalog, making it the first object to be listed when the objects were arranged by right ascension.〔Dreyer, J. L. E., "New General Catalogue of Nebulae and Clusters of stars (1888)", ''Memoirs of the Royal Astronomical Society'', 49. p3, Royal Astronomical Society, 1962.〕 Since then, the coordinates have shifted, and this object no longer has the lowest right ascension of all the NGC objects.〔Erdmann, R.E., Jr., ''The Historically Corrected New General Catalogue of Nebulæ and Clusters of Stars'', p12, (retrieved ) and (archived ) 13 June 2008.〕 ==References== : * (http://seds.org/ ) : * (http://backword.me.uk/ ) 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「NGC 1」の詳細全文を読む スポンサード リンク
