NGC 7012 is a large, bright[2] elliptical galaxy located about 380 million Light-years away from Earth in the constellation Microscopium[3][4] NGC 7012 was discovered by astronomer John Herschel on July 1, 1834.[5]

Abell S0921[edit]

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]
