NGC 5308is an edge-onlenticular galaxyin theconstellationofUrsa Major.It was discovered on 19 March 1790 byWilliam Herschel.[5]It was described byJohn Louis Emil Dreyeras "bright, pretty large" when he compiled theNew General Catalogue.[6]A small, irregular galaxy near NGC 5308 has been given the designation LEDA 2802348.[7]
NGC 5308 was imaged by theHubble Space Telescopein 2016. The galaxy appears to be a flat, smooth disk, typical of most lenticular galaxies. Many largeglobular clustersorbit the galaxy; these are visible as tiny dots surrounding the galaxy, and are mostly made of old, agingstarssimilar to the galaxy itself.[8]
SN 1996bk,atype Ia supernova,was discovered in NGC 5308 in October 1996. The supernova was 10.5 "south and 17.9" west of center of the galaxy, and had anapparent visual magnitudeof 15.[9]
