 However, Houk and Cowley (1975) classified it as G2.5 IV, suggesting it is instead a somewhat more evolved subgiant star.It has an estimated 1.32 times the mass of the Sun and 1.46 times the Sun's radius.The star is radiating about 2.24 times the Sun's luminosity from its photosphere at an effective temperature of 5,849 K. It is around 4.6 billion years old and is spinning with a leisurely projected rotational velocity of 3.1 km/s.
