NGC 3947
NGC 3947 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 6528 ± 23 km/s, which corresponds to a Hubble distance of 314.0 ± 22.0 Mly (96.28 ± 6.75 Mpc). In addition, three non redshift measurements give a distance of 284.67 ± 12.90 Mly (87.28 ± 3.956 Mpc). It was discovered by German-British astronomer William Herschel on 26 April 1785.
NGC 3947 has a supermassive black hole with an estimated mass of 9.4 × 107 M☉.
Four supernovae have been observed in NGC 3947:
NGC 3947 is a member of the NGC 3937 Group, which is part of the Coma Supercluster.
