HD 75710 is a single [8] star in the constellation of Vela. It has an apparent visual magnitude of approximately 4.94, [2] which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of 2.7 mas, [1] 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. [6] HD 75710 is radiating 914 times the Sun's luminosity from its photosphere at an effective temperature of 8,150 K. [5]
