GR 8 (also known as UGC 8091) is a gas-rich dwarf irregular galaxy. In 1995, Tolstoy et al. estimated its distance (with the Hipparcos correction of 1997 applied) to be approximately from Earth. It is around 2.8 Mly from UGC 9128. It is still an open question whether it is a member of the Local Group or possibly the Virgo Cluster.
GR 8 was discovered at the Lick Observatory using the 20-inch astrograph in either 1946, 1947, or 1951.
