This is an ordinary A-type main-sequence star with a stellar classification of A3Vn,[3] where the 'n' suffix indicates "nebulous" (broadened) lines due to rapid rotation. It is about 182[8] million years old with a high projected rotational velocity of 201 km/s.[6] The star has 2.5[6] times the mass of the Sun and 2.1[7] times the Sun's radius. It is radiating 55[6] times the luminosity of the Sun from its photosphere at an effective temperature of 9,902 K.[8]
