It was discovered by Pierre Méchain in 1781, and catalogued by Charles Messier four days later.
Contents
Nucleus
The center of the galaxy contains a ring-shaped circumnuclear star-forming region with a diameter of approximately 2000 ly (600 pc).[3]
Galaxy group information
M95 is one of several galaxies within the M96 Group, a group of galaxies in the constellation Leo. The group also includes the Messier objects M96 and M105.[4][5][6][7]
