This object is a G-type main-sequence star with a stellar classification of G3VFe0.5, where the suffix notation indicates a mild overabundance of iron. It is roughly two billion years old and is spinning with a projected rotational velocity of 5 km/s. This is a solar-type star with 5% greater mass compared to the Sun and 1.24 times the Sun's radius. The star is radiating 1.19 times the luminosity of the Sun from its photosphere at an effective temperature of 5,386 K.
