The Phoenix Dwarf has an inner part of young ]s which is stretched in an east-west direction and an outer part of mainly old stars that is stretched north-south. The central region's rate of ] seems to have been relatively constant across time (Martínez-Delgado et al. 1999). In 1999, St-Germain et al. discovered a ] region of about 10<sup>5</sup> {{Solar mass|link=y}} just to the west of Phoenix. Its ] is -23 km/s and may be physically associated with Phoenix if it is found to have a similar radial velocity. the phoenix galaxy is 1.4 million light years away and contains approxametly a few billion <ref name="Bergh2000">{{Cite journal

The Phoenix Dwarf has an inner part of young stars which is stretched in an east-west direction and an outer part of mainly old stars that is stretched north-south. The central region's rate of star formation seems to have been relatively constant across time (Martínez-Delgado et al. 1999). In 1999, St-Germain et al. discovered a H I region of about 10 M☉ just to the west of Phoenix. Its radial velocity is -23 km/s and may be physically associated with Phoenix if it is found to have a similar radial velocity.
