This object is a B-type main-sequence star with a stellar classification of B4V,[3] which indicates it is undergoing core hydrogen fusion. The star has a radius of nearly four times the radius of the Sun,[5] and over six[4] times the Sun's mass. Age estimates range from 17[4] up to 176[8] million years old, and it is spinning with a projected rotational velocity of 43 km/s.[6] It is radiating 912[6] times the luminosity of the Sun from its photosphere at an effective temperature of 16,983 K.[6]
