NGC 4277
Galaxy in the constellation Virgo
From Wikipedia, the free encyclopedia
NGC 4277 is an intermediate spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2,533±24 km/s, which corresponds to a Hubble distance of 121.9 ± 8.6 Mly (37.37 ± 2.64 Mpc).[1] It was discovered by German-British astronomer William Herschel on 17 April 1786.[2]

NGC 4277 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[3][4]
