NGC 2814 is a small spiral galaxy in the constellation Ursa Major. Its velocity relative to the cosmic microwave background is 1,693 ± 8 km/s, which corresponds to a Hubble distance of 25.0 ± 1.8 Mpc (~81.5 million light years.). [1] German-British astronomer William Herschel discovered this galaxy on 3 April 1791.
NGC 2814 has a luminosity class of II. [1]
NGC 2814 has three galactic neighbours: the side-on spiral galaxy NGC 2820; the irregular galaxy IC 2458; and the face-on non-barred spiral galaxy NGC 2805. Collectively, the four galaxies make up the galaxy group known as Holmberg 124. [2]
One supernova has been observed in NGC 2814: SN 2020mmz ( type II, mag. 17). [3]
