UGC 8091 (also known as GR 8) is a gas-rich dwarf irregular galaxy. In 1995, Tolstoy et al. estimated its distance to be (with the Hipparcos correction of 1997 applied) ~7.9 Million light-years from Earth. There is still open question regarding if it is a member of the Local Group. It was discovered at the Lick Observatory using the 20-inch astrograph in either 1946, 1947, or 1951.
