__NOTOC__ NGC 262 (also known as Markarian 348) is a huge lenticular galaxy in the cluster LGG 14.〔 It is a Seyfert 2 lenticular galaxy (S0a) located 202 million light years away in the constellation Andromeda. It was discovered in September 17, 1885 by Lewis A. Swift. ==Size== This galaxy has an apparent diameter of approximately 2.6 million light-years (1.1'). It holds approximately more than 15 trillion stars. NGC 262 was tidally disturbed by the gravitational forces of smaller galaxies, which resulted in its tremendous size.〔(【引用サイトリンク】 work=DISTANT GALAXY FOUND TO BE LARGEST KNOWN )〕 NGC 262 is very unusual, since it is 10 times larger than a regular spiral galaxy of its type. According to Morris and Wannier, NGC 262 is surrounded by a huge cloud of neutral hydrogen〔 that is probably caused by the tidal stripping of smaller galaxies. The cloud has an apparent mass of approximately 50 billion solar masses〔 at a distance of 88 kiloparsecs (287,000 light years) 〔 from the nucleus of NGC 262 and extending up to 300 kiloparsecs (1 million light years) away.〔 The cloud is spiral shaped with at least one arm, and possibly another one extending throughout the galaxy. 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 262」の詳細全文を読む スポンサード リンク
