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.
NGC 2283 forms a physical pair with galaxy IC 2171, collectively named RR 140, with an optical separation of 1593″ between them.
SIMBAD lists NGC 2283 as an active galaxy nucleus candidate.
One supernova has been observed in NGC 2283: SN 2023axu (Type II, mag. 15.6404) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 28 January 2023.
