 The metallicity is very low, at about =−1.6 to −1.9 meaning that Antlia Dwarf contains 40–80 times less heavy elements than the Sun.The galaxy has a well-defined and easily observed red giant branch, which makes measuring its distance relatively easy.The total luminosity of Antlia Dwarf is approximately 1 million times that of the Sun (the visible absolute magnitude is MV=−10.3).
