NGC 3972 is a spiral galaxy located in the northern constellation of Ursa Major. It was discovered by William Herschel on April 14, 1789. This galaxy is located 66 million light years away and is receding with a heliocentric radial velocity of 846 km/s. It is a member of the NGC 3992 Group of galaxies.
NGC 3972 with NGC 3977 NGC 3972 along with NGC 3977 are listed together as Holm 304 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.
