NGC 7012 is a large, bright elliptical galaxy located about 380 million light-years away from Earth in the constellation Microscopium.[2] [3] NGC 7012 was discovered by astronomer John Herschel on July 1, 1834.[4] NGC 7012 is also is host to a supermassive black hole with an estimated mass of 4.5 × 109 M☉.[5] NGC 7012 is very large galaxy, with an estimated diameter of nearly 300,000 light years.
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.[9]
