NGC 5279is a spiral galaxy in the constellationUrsa Major.It was discovered by German-BritishastronomerWilliam Herschelin 1789. NGC 5279 is ingravitational interactionwith the galaxyNGC 5278.This pair of galaxies appears inHalton Arp'sAtlas of Peculiar Galaxies[1]under the designation Arp 239.[2]The luminosity class of NGC 5279 is I1. NGC 5279 is a galaxy whose core shines in theultraviolet region.It is listed in theMarkarian catalogunder the designation Mrk 271 (MK 271).[3]
NGC 5278 Group[edit]
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 sphereisPGC 48439.With a radial speed of 11,939 km/s, this galaxy is almost two times further away than the members of this trio.
