This is an ordinary F-type main-sequence star with a stellar classification of F0 V. At the estimated age of two billion years, it is about 55% of the way through its main sequence lifetime and still has a relatively high rate of spin with a projected rotational velocity of 105.9 km/s. The star has 1.5 times the mass of the Sun and is radiating 6.3 times the Sun's luminosity at an effective temperature of 6,850 K.
