The primary component is a G-type main-sequence star with a stellar classification of G8V, which is slightly less massive and slightly dimmer than the Sun. This is an RS Canum Venaticorum variable star with its luminosity varying by 0.033 magnitudes over a period of 18 days. Compared to the Sun, it has more than double the abundance of elements more massive than helium—what astronomers term the star's metallicity.
