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]

Supermassive black hole

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]
