M96 Group
Template:Short description Script error: No such module "redirect hatnote". Template:Sky Template:Galaxy cluster
The M96 Group (also known as the Leo I Group) is a group of galaxies in the constellation Leo. This group contains between 8 and 24 galaxies, including three Messier objects.[1][2][3][4] It also contains the Leo Ring. The group is one of many groups that lies within the Virgo Supercluster (the combined Local Group and Virgo cluster).[5]
Members
The table below lists galaxies that have been consistently identified as group members in the Nearby Galaxies Catalog,[3] the survey of Fouque et al.,[4] the Lyons Groups of Galaxies (LGG) Catalog,[1] and the three group lists created from the Nearby Optical Galaxy sample of Giuricin et al.[2]

Nearby groups
The Leo Triplet, which includes the spiral galaxies M65, M66, and NGC 3628,[1][2][3] is located physically near the M96 Group.[8] Some group identification algorithms actually identify the Leo Triplet at part of the M96 Group.[2][4] The two groups may actually be separate parts of a much larger group.[8]
