SIMBAD data

HD 83332 (HR 3830) is a solitary, [13] orange hued star located in the southern constellation Antlia. It has an apparent magnitude of 5.68, [3] making it faintly visible to the naked eye if viewed under ideal conditions. The star is located 285 light years [2] away based on its annual parallax shift, but is drifting away with a radial velocity of 30  km/s . [6]

HD 83332 has a classification of K0 III, [4] which suggests it is an evolved giant star. At present it has 1.6 [7] times the mass of the Sun and at an age of 2.7 billion years, [2] has expanded to a radius of 10.6  R☉ . It radiates at 55 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,610 K. [7] HD 83332 has a solar metallicity, 112% that of the Sun to be exact, and is a member of the thin disk. [10]
