Elliptical radio galaxy in the constellation Andromeda
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]
3C 66B is an outlying member of Abell 347 which is part of the Perseus–Pisces Supercluster .[ 8]
