HD 75710 is a single[9] star in the constellation of Vela. It has an apparent visual magnitude of approximately 4.94,[1] which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of Script error: No such module "val".,[2] it is located about 1,200 light-years from the Sun.

The stellar classification of this star is A2 III,[3] suggesting it is in the giant star stage of its stellar evolution. It has a high rate of spin with a projected rotational velocity of 110 km/s, which is giving the star an oblate shape with an equatorial bulge that is 7% larger than the polar radius.[7] HD 75710 is radiating 1,668 times the Sun's luminosity from its photosphere at an effective temperature of Script error: No such module "val"..[6]
