UGC 9405 (also known as PGC 52142) is a faint dwarf irregular galaxy situated in the constellation of Ursa Major.

It is about 20.5 million light-years, or 6.3 megaparsecs, away from the Earth.

[3] It is listed as a member of the M101 Group, a group containing the several galaxies orbiting the largest, Pinwheel Galaxy (M101).

[5] However, due to its far distance from the Pinwheel Galaxy, its membership of the group is uncertain.
