NGC 1281 is a compact [3] elliptical galaxy [4] located about 200 million light-years away [3] in the constellation Perseus. [5] NGC 1281 was discovered by astronomer John Dreyer on December 12, 1876. [6] It is a member of the Perseus Cluster. [7] [6]
Like NGC 1277 and NGC 1271, NGC 1281 is a candidate " relic galaxy". [8]
The supermassive black hole in NGC 1281 has an estimated mass of about 10 billion solar masses (1010 M☉). [3] However, Anna Ferré-Mateu et al. estimated the black hole has a mass of no more than 5 billion solar masses. [8]
