This is an aging giant star with a stellar classification of G8III. It is cooling and expanding along the red giant branch, having evolved off the main sequence after exhausting its core supply of hydrogen fuel. At present it has 10 times the Sun's radius. Mass estimates range from 1.21 up to 2.32 times the mass of the Sun. The star has a lower metallicity the Sun – what astronomers term the abundance of elements with more mass than helium – and it is spinning with a projected rotational velocity of 3.3 km/s. It is radiating 50.5 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,793 K.
