Messier 96 (also known as NGC 3368) is an intermediate spiral galaxy about 31 million light-years away in the constellation Leo. It was discovered by Pierre Méchain in 1781.
[edit] M96 Group
M96 is the brightest galaxy within the M96 Group, a group of galaxies in the constellation Leo also includes the Messier objects M95 and M105, as well as at least nine other galaxies.[3][4][5][6] The M96 galaxy has asymmetric arms and a displaced core, probably caused by the gravitational pull by the other nearby galaxies.
