3C 66B is an elliptical Fanaroff and Riley class 1 radio galaxy[2] located in the constellation Andromeda. With an estimated redshift of 0.021258,[1] the galaxy is about 300 million light-years away.[2]

The orbital motion of 3C 66B showed supposed evidence for a supermassive black hole binary (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 an active galactic nucleus. The smooth jet of 3C 66B rivals that of M87.[7]
