HD 75063 is a single[9] star in the southern constellation of Vela. It has the Bayer designation of a Velorum, while HD 75063 is the identifier from the Henry Draper Catalogue. This is a naked-eye star with an apparent visual magnitude of 3.87[1] and has a white hue. The star is located at a distance of approximately 1,900 light-years from the Sun based on parallax measurements and has an absolute magnitude of −4.89.[1] It is drifting further away with a radial velocity of +23 km/s.[1]
This object has been stellar classifications of A1III[3] and A0 II,[4] matching a massive A-type giant or bright giant star, respectively. It is an estimated 31 million years old[5] and is spinning with a projected rotational velocity of 30 km/s.[7] The star has 8.6 times the mass of the Sun[5] and around 4.5 times the Sun's radius. The star is radiating 6,800 times the Sun's luminosity from its photosphere at an effective temperature of Script error: No such module "val"..[5]
