Messier 105 (also known as M105 and NGC 3379) is an w:elliptical galaxy in the w:constellation Leo. Messier 105 is known to have a w:supermassive black hole.
History
Messier 105 was discovered by w:Pierre Méchain on 24 March w:1781, just a few days after he discovered the nearby galaxies w:Messier 95 and w:Messier 96.[3] This galaxy is one of several that were not originally included in the original w:Messier Catalogue compiled by w:Charles Messier. Messier 105 was included in the catalog only when w:Helen S. Hogg found a letter by Méchain describing Messier 105 and when the object described by Méchain was identified as a galaxy previously named NGC 3379.[3]
Galaxy group information
Messier 105 is one of several galaxies within the w:M96 Group, a w:group of galaxies in the w:constellation Leo. The group also includes the w:Messier objects M95 and M96.[4][5][6][7]
