The M101 Group is a loose group of galaxies located in the constellation Ursa Major. The group is named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). Most of the other members of the group are companions of the Pinwheel Galaxy.[1][2][4][3] The group itself is one of many located within the Virgo Supercluster (i.e. the Local Supercluster).[5]
