HD 75063 is a single [10] 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 [2] 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. [2] It is drifting further away with a radial velocity of +23 km/s. [2]
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 [5] million years old and is spinning with a projected rotational velocity of 30 km/s. [8] The star has 8.6 [5] times the mass of the Sun and around 4.5 [6] times the Sun's radius. The star is radiating 8,670 [2] times the Sun's luminosity from its photosphere at an effective temperature of 8,023 K. [7]
