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] NGC 7012 is host to a supermassive black hole with an estimated mass of 4.5 × 109 M☉.[6] NGC 7012 is very large galaxy, with an estimated diameter of nearly 300,000 light years.[4]

Abell S0921

NGC 7012 is the brightest member in the center of a small compact group of interacting galaxies[7] known as Abell S0921.[8] Due to it also being the dominant member of the group, NGC 7012 is classified as a Cd galaxy.[9] The group has about seven major galaxies with many other more distant, fainter galaxies that are probably also associated.[2]
