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]
