HR 4339, once known as Beta Antliae, is a main sequence star in the constellation Hydra. Located around 390 light-years distant, it shines with a luminosity approximately 60 times that of the Sun and has a surface temperature of 8886 K.[2]

This star was designated as Beta Antliae by Lacaille, and Gould intended to keep it in that constellation. However, the delineating of constellation boundaries in 1930 saw it transferred to Hydra.[3]
