This is a white-hued A-type main-sequence star with a stellar classification of A4Vn,[4] where the 'n' notation indicates "nebulous" absorption lines due to rapid rotation. It is an estimated 345[5] million years old and is spinning with a projected rotational velocity of 249 km/s.[3] The star has 1.80[3] times the mass of the Sun and is radiating 13 times the Sun's luminosity from its photosphere at an effective temperature of 7,798 K.[3]
