NGC 1281 is a compact elliptical galaxy[3] located about 200 million light-years away[4] 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] 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 (M☉). However, Anna Ferré-Mateu et al. estimated the black hole has a mass of no more than 5 billion solar masses.
