Sh2-2
Sh 2-2, also known as Sharpless 2, is an emission nebula in the constellation of Scorpius. It appears as a mid-range brightness making it difficult to view. It is believed to currently host a X-ray binary star that originated and was ejected from the Scorpius OB1 association. The nebulous area is fairly large with an irregular shape appearing as a H II region.〔(【引用サイトリンク】url=http://www.sharplesscatalog.com/Sharpless.aspx?sharp=2 )〕 The remnant has an apparent diameter that covers approximately 60'. ==References==
