With an age of 420 million years, this is a red giant star with a stellar classification of G8 III,^[3] indicating it has consumed the hydrogen at its core and evolved off the main sequence. It has 2.8 times the mass of the Sun and has expanded to 12 times the Sun's radius. The star is radiating 90 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 5,107 K.^[5]
