This is an ordinary G-type main-sequence star with a stellar classification of G0V. The luminosity class of 'V' indicates the star is generating energy through core hydrogen fusion. It is about two billion years old and is spinning slowly with a projected rotational velocity of 3 km/s. The abundance of elements other than hydrogen and helium in the star – what astronomers term metallicity – is about the same as in the Sun. It has 17% more mass than the Sun and an 18% greater radius. The star is radiating 1.85 times the luminosity of the Sun from its photosphere at an effective temperature of 6,200 K.
A survey in 2015 has ruled out the existence of any stellar companions at projected distances above 23 astronomical units. However, in 2019 a white dwarf companion to this star was found.
