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