The spectrum of this object is that of a subgiant star with a stellar classification of G7 IV, which would suggest it has exhausted the supply of hydrogen at its core and has begun to evolve into a giant star. It is around 1.7 billion years old with a projected rotational velocity of 1.8 km/s. The star has nearly double the mass of the Sun and almost six times the Sun's radius. It is radiating 20 times the luminosity of the Sun from its photosphere at an effective temperature of 5,044 K.
