The M51 group of galaxies

A smaller galaxy group at a distance of 37 million light years.

Messier objects: M51, M63.

R. Brent Tully's Nearby Galaxies Catalog lists a total of 8 members of this group; in addition to the two Messier galaxies and M51's companion NGC 5195, they are: NGCs 5023 and 5229 as well as UGCs 8313, 8331 and 8683.

This group is rather loose and clearly dominated by the two Messier galaxies.

The following table lists some data for the galaxies in the M51 group:
