HD 83332 (HR 3830) is a star, located in the southern constellation Antlia. With an apparent magnitude of 5.68,[2] it is faintly visible to the naked eye under ideal conditions. The star is located 296 light years[1] away based on its parallax shift, but is drifting away with a radial velocity of 30 km/s.[5]

HD 83332 has a classification of K0 III,[3] which suggests it is a star that has exhausted hydrogen at its core and left the main sequence. At present it has 1.21[6] times the mass of the Sun, but has expanded to nearly 11 times its girth. It radiates at 52.7 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,718 K,[1] which gives it the typical orange hue of a K-type star; it has a solar metallicity.[7]
