NGC 6215 (also known as PGC 59112) is a spiral galaxy located in the constellation Ara. It is designated as SA(s)c in the galaxy morphological classification scheme. It was discovered by astronomer John Herschel on 9 July 1836.[1][2][3]
Galaxy group information
[edit]NGC 6215 is part of galaxy group NGC 6221/15, which includes barred spiral galaxy NGC 6221 and three dwarf galaxies. A double-stranded bridge of neutral hydrogen gas connects NGC 6215 and 6221 as a result of their interaction, and Dwarf 3 of the three dwarf galaxies may have formed from the bridging gas.[4]
