In 1975 Tully & Fisher determined that it was part of the Local Group. The metallicity and the related distance estimate has been subject to discussions in the scientific literature, with varying results, however, recently, by use of the tip of the red giant branch, a distance within 10% error was achieved in 2000 and then improved to 3% in 2005.

This galaxy is presumed to be the primary location of the 2004-2009 science fiction television series Stargate Atlantis. While it's mentioned the show takes place in "the Pegasus galaxy" it has not explicitly stated if it is the Irregular or Spheroidal. However, when the Pegasus galaxy has been seen from the Midway station an irregular galaxy is shown. Also, in the discussion regarding the new McKay–Carter Intergalactic Gate Bridge, General Hank Landry states that the distance between the Pegasus and Milky Way galaxies is "three million light-years", suggesting that the series takes place in the Pegasus Dwarf Irregular Galaxy.
