Messier 95 (also known as M95 or NGC 3351) is a barred spiral galaxy about 38 million light-years away[citation needed] in the constellation Leo. It was discovered by Pierre Méchain in 1781, and catalogued by Charles Messier 4 days later.

[edit] Nucleus

The center of the galaxy contains a ring-shaped circumnuclear star-forming region with a diameter of approximately 2000 ly (600 pc)[2].

[edit] 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[3][4][5][6].
