This is an A-type main-sequence star with a stellar classification of A0 Vn,^[4] where the 'n' notation indicates "nebulous" lines due to rapid rotation. In the past it was misidentified as a Lambda Boötis star.^[11] It is around 400^[7] million years old and is spinning with a projected rotational velocity of 217 km/s.^[8] The star has 2.8^[3] times the mass of the Sun and 3.3^[7] times the Sun's radius. It is radiating 97^[3] times the Sun's luminosity from its photosphere at an effective temperature of 9,748 K.^[3]

An infrared excess indicates it has a dusty debris disk with a mean temperature of 120 K orbiting at a distance of 52 AU from the star. This disk has a combined mass equal to 2.1% the mass of the Earth.^[7]
