NGC 3949 is an unbarred spiral galaxy in the constellation Ursa Major. It is believed to be approximately 50 million light-years away from the Earth. NGC 3949 is a member of the M109 Group, a group of galaxies located in the constellation Ursa Major that may contain over 50 galaxies. The brightest galaxy in the group is the spiral galaxy M109. [2] [3] [4]
The type II supernova SN 2000db is the only supernova that has been observed within NGC 3949. [1]
