NGC 3953 is a barred spiral galaxy located in the constellation Ursa Major. Its velocity with respect to the cosmic microwave background is 1,236±13 km/s, which corresponds to a Hubble distance of 59.4 ± 4.2 Mly (18.22 ± 1.29 Mpc). However, 33 non-redshift measurements give a closer mean distance of 54.10 ± 1.93 Mly (16.588 ± 0.592 Mpc). It was discovered by Pierre Méchain on 12 March 1781.
