NGC 873 is a peculiarspiral galaxy in theconstellation ofCetus. Its velocity with respect to thecosmic microwave background is3,777±17 km/s, which corresponds to aHubble distance of 181.7 ± 12.8 Mly (55.70 ± 3.91 Mpc).[1] It was discovered by German-British astronomerWilliam Herschel on 27 November 1785.[2][3]
NGC 873 has a possibleactive 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]
NGC 873 is a member of the NGC 835 galaxy group (also known asLGG 49). The other galaxies in the group areNGC 833,NGC 835,NGC 838,NGC 839,NGC 848, andUGCA 23.[6][7]
