 They for the first time resolved it into stars and determined the distance to it—1.15 Mpc (the modern distance estimate is slightly larger).In 1999 Antlia Dwarf was identified by Sidney van den Bergh as the fourth member of the Antlia Group—the group of galaxies closest to the Local Group.The Antlia Dwarf is classified alternatively as a dwarf elliptical galaxy of type dE3.5, or either as a dwarf spheroidal galaxy (dSph) or as a transitional galaxy from spheroidal to irregular types (dSph/Irr).
