NGC 7316 is a barred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 5,198±25 km/s, which corresponds to a Hubble distance of 250.1 ± 17.5 Mly (76.67 ± 5.38 Mpc).^[1] However, three non-redshift measurements give a closer mean distance of 212.87 ± 3.89 Mly (65.267 ± 1.192 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 18 September 1784.^[3]^[4]

NGC 7316 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.^[5]^[6] NGC 7316 is also a starburst galaxy.^[1]

NGC 7316 has a nucleus with excessive amounts of ultraviolet emissions compared with other galaxies, and is listed in the Markarian catalogue as MRK 307.^[7]

Galaxy group

According to M. J. Geller and J. P. Huchra, NGC 7316 is a member of a galaxy group which contains 2 other galaxies: NGC 7321 and NGC 7323 [fr].^[8]

Supernovae

Two supernovae have been observed in NGC 7316:

SN 2006cx (Type II, mag. 17.4) was discovered by the Lick Observatory Supernova Search (LOSS) on 8 June 2006.^[9]^[10]
SN 2016hvu (Type II-P, mag. 17.6) was discovered by the Catalina Real-time Transient Survey on 6 November 2016.^[11]^[12]
