Messier 105 (also known as M105 and NGC 3379) is an elliptical galaxy in the constellation Leo. Messier 105 was discovered by Pierre Méchain 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 originalMessier Catalogue compiled by Charles Messier. Messier 105 was included in the catalog only when 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.
Messier 105 is known to have a supermassive black hole whose mass is estimated to be between 1.4·108 and 2·108 solar masses.[4] It also contains a few young stars and stellar clusters, suggesting some elliptical galaxies still form new stars, but very slowly.[1]
