NGC 7012 is a large, bright elliptical galaxy located about 380 million light-years away from Earth in the constellation Microscopium. NGC 7012 was discovered by astronomer John Herschel on July 1, 1834. NGC 7012 is host to a supermassive black hole with an estimated mass of 4.5 billion M☉. NGC 7012 is very large galaxy, with an estimated diameter of nearly 550,000 light years.

Abell S0921

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