NGC 5371 is a face-onspiral galaxy in the northernconstellationCanes Venatici. It was discovered on January 14, 1788 by German-British astronomerWilliam Herschel. The nearbyNGC 5390 appears to be a duplicate entry for NGC 5371, since there is nothing at the former's position.[8] NGC 5371 has anapparent magnitude of 11.3 and anangular size of4.4′ × 3.5′.[5] It is located at a distance of 129.5 ± 32.4 millionlight-years (39.70 ± 9.92 Mpc) from theMilky Way,[4] and is receding with a heliocentricradial velocity of 2,552 km/s. The galaxy appears to be weakly interacting with the nearby, equidistantHickson 68 group of galaxies, and thus may be a member.[3] Collectively, they are sometimes dubbed the Big Lick galaxy group, after the city ofRoanoke, Virginia.[9]

Themorphological classification of NGC 5371 in the De Vaucouleurs system is SAB(rs)bc,[5] indicating a weakly barred spiral galaxy (SAB) with a transitional inner ring structure (rs), and moderately wound spiral arms (bc). Thegalactic plane is inclined at an angle of45°±5° to theplane of the sky, with the major axis oriented along aposition angle of195°±3°.[10] This is classified as aLINER-type galaxy and may be in a post-starburst phase. There is an extended or doublesource of X-ray emission.[11]
Twosupernovae have been observed in NGC 5371.Type II-L supernova SN 1994Y was spotted on August 19, 1994, reaching peakB magnitude of 14.2 on August 30.[12]Type IIb supernova SN 2020bio was discovered January 29, 2020. The progenitor may have undergone extensive mass loss, shedding nearly all of its hydrogen envelope.[13]
