NGC 3319 is abarred spiral galaxy in the constellationUrsa Major. It was discovered byWilliam Herschel on Feb 3, 1788.[5] It is rich in gas and lacks agalactic bulge.[3]

NGC 3319 is relatively isolated. It is in a small group of galaxies includingNGC 3104,NGC 3184, andNGC 3198. The nearest galaxy to it is probably NGC 3198, 4.2 million light-years (1.3 megaparsecs) away.[3]

NGC 3319 is aSeyfert galaxy, with anactive galactic nucleus (AGN) that was identified in 2018.[6] NGC 3319 is a candidate for hosting anintermediate-mass black hole. The probability of having the black hole having a mass less than 105 M☉ has been placed at 84%.[3]
