From Wikipedia, the free encyclopedia
NGC 7002 is a large elliptical galaxy,[2] and a radio galaxy,[3] around 320 million light-years away from Earth in the constellation of Indus.[4][2] The galaxy was discovered by English astronomer John Herschel on September 30, 1834.[5] NGC 7002 is the brightest member of a group of galaxies[6] known as [T2015] nest 200093.[7] The group contains 12 member galaxies including NGC 7004, has a velocity dispersion of 440 km/s and an estimated mass of 1.28 × 1014 M☉.[6] NGC 7002 is also host to a supermassive black hole with an estimated mass of 2.7 × 109 M☉.[8]
