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]
