Characteristics

Paul W. Hodge analyzed the distribution of its stars in 1964 and concluded that its ellipticity was 0.29 ± 0.04.Recent studies have indicated that the galaxy may potentially hold large amounts of dark matter. Having an absolute magnitude of -8.6 and a total luminosity of only 2 L<sub>☉</sub>, it is one of the faintest companions to our Milky Way.

Draco Dwarf contains many red giant branch (RGB) stars; five carbon stars have been identified in Draco Dwarf and four likely asymptotic giant branch (AGB) stars have been detected.
