NGC 873

NGC 873 is a peculiar spiral galaxy in the constellation of Cetus. Its velocity with respect to the cosmic microwave background is 3,777±17 km/s, which corresponds to a Hubble distance of 181.7 ± 12.8 Mly (55.70 ± 3.91 Mpc).^[1] It was discovered by German-British astronomer William Herschel on 27 November 1785.^[2][3]

NGC 873 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.^[4][5]
