This star has been assigned a stellar classification of F8 V,[3] which indicates it is an ordinary F-type main-sequence star. However, Gray et al. (2001) gave it a class of F9 IV, suggesting it is instead a subgiant star that is evolving away from the main sequence as the hydrogen fuel at its core becomes exhausted.[8] It is an estimated 2.6 billion years old and is rotating with a period of 15.2 days. The star has 1.64 times the mass of the Sun and 3.6 times the Sun's radius. It is radiating 13 times the Sun's luminosity from its photosphere at an effective temperature of 6,028 K.[3] It appears overluminous for a star of its type which may indicate the presence of a bright companion, but no radial velocity variation has been detected.[9]
