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).[1] It was discovered by German-British astronomer William Herschel on 6 February 1785.[2]

NGC 2283 forms a physical pair with galaxy IC 2171, collectively named RR 140, with an optical separation of 1593″ between them.[3]

SIMBAD lists NGC 2283 as an active galaxy nucleus candidate.[4]

One supernova has been observed in NGC 2283: SN 2023axu (type II, mag 15.64) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 28 January 2023.[5]
