Xi Aurigae is a single,[9] white-hued star in the northern constellation of Auriga. Its name is a Bayer designation that is Latinized from ξ Aurigae, and abbreviated Xi Aur or ξ Ari. This star was once considered part of the constellation of Camelopardalis and held the Flamsteed designation 32 Camelopardalis.[10] It is visible to the naked eye with an apparent visual magnitude of +5.0.[3] The measured annual parallax shift of this star is Script error: No such module "val".,[2] which corresponds to a physical distance of Script error: No such module "convert". with a 3 light-year margin of error. At that distance, the visual magnitude of the star is diminished by an extinction of 0.108 due to interstellar dust.[11] The star is drifting closer to the Sun with a radial velocity of −13 km/s.[5]
This is an A-type main sequence star with a stellar classification of A2 Va.[4] Although it was one of the first stars to be cataloged as a Lambda Boötis star, Murphy et al. (2015) don't consider it to be a member of this population.[4] The star has nearly twice[6] the mass of the Sun and about 1.1[7] times the Sun's radius. It is an estimated 174[6] million years old and is spinning with a projected rotational velocity of 62 km/s.[6] Xi Aurigae is radiating 49.5[1] times the Sun's luminosity from its photosphere at an effective temperature of around 9,152 K.[6]
