This is an F-type main sequence star with a stellar classification of F6 V. It is about 1.3 billion years old with a projected rotational velocity of 14 km/s and exhibits a low level of activity. The star has an estimated 1.34 times the mass of the Sun and 1.45 times the Sun's radius. It is radiating 2.82 times the solar luminosity from its photosphere at an effective temperature of 6,324 K. This star is a candidate for hosting a debris disk, having initially shown a near-infrared excess, which diminished with further observations.
