3C 66Bis anelliptical Fanaroff and Riley class 1 radio galaxy^[2]located in theconstellation Andromeda.With an estimatedredshiftof 0.021258,^[1]the galaxy is about 300 millionlight-yearsaway.^[2]

The orbital motion of 3C 66B showed supposed evidence for asupermassive black holebinary (SMBHB) with a period of 1.05 ± 0.03 years,^[5]but this claim was later proven wrong (at 95% certainty).^[6]

Messier 87(M87), about 55 million light-years away, is the largest giant elliptical galaxy near the Earth, and also contains anactive galactic nucleus.The smoothjetof 3C 66B rivals that of M87.^[7]

3C 66B is an outlying member ofAbell 347which is part of thePerseus–Pisces Supercluster.^[8]
