HD 95370
Star in the constellation Vela
From Wikipedia, the free encyclopedia
HD 95370 is a single[8] star in the southern constellation of Vela. With an apparent visual magnitude of 4.37,[1] it can be viewed with the naked eye. The distance to this star can be determined from its annual parallax shift of 16.2 mas,[2] yielding a value of 201 light years. It is moving closer to the Earth with a heliocentric radial velocity of −3.5 km/s.[1]

According to Houk (1978), this is an A-type main-sequence star with a stellar classification of A3 V.[3] However, Levato (1972) listed a class of A3 IV, which may suggest it is instead a more evolved subgiant star. It is 548 million years[4] years old with a high projected rotational velocity of 115 km/s, giving it an oblate shape with an equatorial bulge that is 5% larger than the polar radius.[6] HD 95370 has double[4] the mass of the Sun and 2.6[5] times the Sun's radius. It is radiating 55[1] times the Sun's luminosity from its photosphere at an effective temperature of 8,696 K.[4]
