NGC 5279 is a spiral galaxy in the constellationUrsa Major. It was discovered by German-BritishastronomerWilliam Herschel in 1789. NGC 5279 is ingravitational interaction with the galaxyNGC 5278. This pair of galaxies appears inHalton Arp'sAtlas of Peculiar Galaxies[2] under the designation Arp 239.[1] The luminosity class of NGC 5279 is I1. NGC 5279 is a galaxy whose core shines in theultraviolet region. It is listed in theMarkarian catalog under the designation Mrk 271 (MK 271).[3]
According toAbraham Mahtessian, NGC 5278 and UGC 8671 form a pair of galaxies. Mahtessian further mentions that NGC 5278 and NGC 5279 form a pair of galaxies. In reality, these galaxies therefore form a trio of galaxies, the group of NGC 5278. The other galaxy in the same region of thecelestial sphere isPGC 48439. With a radial speed of 11,939 km/s, this galaxy is almost two times further away than the members of this trio.
