HD 75710 is a single[ 9] star in the constellation of Vela . It has an apparent visual magnitude of approximately 4.94,[ 1] parallax shift of mas [ 2] light-years from the Sun .
The stellar classification of this star is A2 III,[ 3] 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] Sun's luminosity from its photosphere at an effective temperature of K [ 6]
