NGC 5279 is a spiral galaxy in the constellation Ursa Major. It was discovered by German-British astronomer William Herschel in 1789. NGC 5279 is in gravitational interaction with the galaxy NGC 5278. This pair of galaxies appears in Halton Arp's Atlas 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 the ultraviolet region. It is listed in the Markarian catalog under the designation Mrk 271 (MK 271).[3]
NGC 5278 Group
According to Abraham 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 the celestial sphere is PGC 48439. With a radial speed of 11,939 km/s, this galaxy is almost two times further away than the members of this trio.
