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]
