Messier 95 (also known as M95 or NGC 3351) is a w:barred spiral galaxy about 33 million w:light-years away in the w:constellation Leo. It was discovered by w:Pierre Méchain in w:1781, and catalogued by w:Charles Messier four days later.
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 w:M96 Group, a w:group of galaxies in the w:constellation Leo. The group also includes the w:Messier objects M96 and M105.[4][5][6][7]
