This is an ordinary A-type main-sequence star with a stellar classification of A3 V,[4] which indicates it is generating energy through hydrogen fusion at its core. It has a projected rotational velocity of 44 km/s, with 2.66[3] times the mass of the Sun and double the Sun's radius.[7] The star is radiating 93[3] times the Sun's luminosity from its photosphere at an effective temperature of 8,472 K.[3]
