NGC 2283 is a barred spiral galaxy in the constellation of Canis Major. Its velocity with respect to the cosmic microwave background is 994 ± 11 km/s, which corresponds to a Hubble distance of 14.66 ± 1.04 Mpc (~48 million light-years). It was discovered by German-British astronomer William Herschel on 6 February 1785.{{cite web | url = https://cseligman.com/text/atlas/ngc22a.htm#2283 | title = New General Catalogue Objects: NGC{{nbsp}}2283 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 16 December 2024}}
