M95 (NGC 3351) is a relatively nearby barred spiral galaxy (type SB(r)b) located about 38 million light-years away in the constellation Leo. Messier 95 (M95) is part of the M96 Group of galaxies, which also includes M96 (another spiral) and M105 (an elliptical). It was discovered by Pierre Méchain in 1781.


M95 is remarkable for a ring of very active star formation, centered on the galactic nucleus, which lies just outside the central bar.
