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). However, three non-redshift measurements give a closer mean distance of 212.87 ± 3.89 Mly (65.267 ± 1.192 Mpc). It was discovered by German-British astronomer William Herschel on 18 September 1784.

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. NGC 7316 is also a starburst galaxy.

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.

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].
