NGC 2805 is an intermediate spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 1834 ± 7 km/s, which corresponds to a Hubble distance of 27.05 ± 1.90 Mpc. However, 11 non redshift measurements give a distance of 12.76 ± 11.89 Mpc. The galaxy was discovered by German-British astronomer William Herschel on 2 April 1791.
One supernova has been observed in NGC 2805: SN 2019hsw was discovered by ASAS-SN on 18 June 2019.
