UGC 8837 (also known as Holmberg IV) is a dwarf galaxy located in the constellation of Ursa Major, 24 million light years away from Earth. It is a member of the M101 Group, a group containing several galaxies orbiting the largest, the Pinwheel Galaxy (M101).
It is possible UGC 8837 is one of the galaxies that interacted with the Pinwheel Galaxy and, together with NGC 5474 and NGC 5477, initiated a burst of star formation.
