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]
