NGC 579 is a spiral galaxy in the constellation of Triangulum. Its velocity with respect to the cosmic microwave background is 4,717±20 km/s, which corresponds to a Hubble distance of 226.9 ± 15.9 Mly (69.57 ± 4.88 Mpc).^[1] It was discovered by British astronomer John Herschel on 22 November 1827.^[2]

NGC 579 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]

NGC 507 group

NGC 579 is a member of the NGC 507 group (also known as LGG 26). This large group contains 42 galaxies, of which 21 are in the NGC catalogue, and 5 are in the IC catalogue.^[5][6]

Supernova

One supernova has been observed in NGC 579:

• SN 2007pk (Type IIn, mag. 17.0) was discovered by the Lick Observatory Supernova Search (LOSS) on 10 November 2007.^[7][8]
