NGC 2814 is a smallspiral galaxy in theconstellationUrsa Major. Its velocity relative to thecosmic microwave background is 1,693 ± 8 km/s, which corresponds to aHubble distance of 24.97 ± 1.75Mpc (~81.5 millionlight years.).[1]German-British astronomerWilliam Herschel discovered this galaxy on 3 April 1791.
NGC 2814 has aluminosity class of II.[1]
NGC 2814 has three galactic neighbours: the side-on spiral galaxyNGC 2820; the irregular galaxy IC 2458; and the face-on non-barred spiral galaxyNGC 2805. Collectively, the four galaxies make up the galaxy group known as Holmberg 124.[2][3]
Onesupernova has been observed in NGC 2814: SN 2020mmz (type II, mag. 17) was discovered by theZwicky Transient Facility on 13 June 2020.[4]
