NGC 3953 is a barred spiral galaxy located in the constellation Ursa Major. The galaxy is known to exhibit an inner ring structure that encircles the bar. NGC 3953 is a member of the M109 Group, a large group of galaxies located within the constellation Ursa Major that may contain over 50 galaxies.[2][3][4][5]

Two supernovae have been identified within NGC 3953:[1] the type Ia supernova SN 2001dp[6] and SN 2006bp.[7]
