HD 75710 is a single[8] star in the constellationofVela. 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 shiftof2.7 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 temperatureof8,150 K.[5]
