Messier 105 (also known as M105 and NGC 3379) is an elliptical galaxy in the constellation Leo. Messier 105 is known to have a supermassive black hole.

History

Messier 105 was discovered by Pierre M?chain on 24 March 1781, just a few days after he discovered the nearby galaxies Messier 95 and Messier 96.[3] This galaxy is one of several that were not originally included in the original Messier Catalogue compiled by Charles Messier. Messier 105 was included in the catalog only when Helen S. Hogg found a letter by M?chain describing Messier 105 and when the object described by M?chain was identified as a galaxy previously named NGC 3379.[3]

Galaxy group information

Messier 105 is one of several galaxies within the M96 Group, a group of galaxies in the constellation Leo. The group also includes the Messier objects M95 and M96.[4][5][6][7]
