Abell S0921

NGC 7012 is the brightest member in the center of a small compact group of interacting galaxies[6] known as Abell S0921.[7] Due to it also being the dominant member of the group, NGC 7012 is classified as a Cd galaxy.[8] The group has about seven major galaxies with many other more distant, fainter galaxies that are probably also associated.[2]
