NGC 7014 is an elliptical galaxy located about 210 million light-years away from Earth in the constellation Indus.[4][5][6] NGC 7014 was discovered by English astronomer John Herschel on October 2, 1834.[7] A population of around 1,634 known globular clusters surround the galaxy,[3] and it is also host to a supermassive black hole with an estimated mass of 2.6 × 109 M☉.[8] NGC 7014 is also classified as a type 1 seyfert galaxy.[9]
