It is faintly visible to the naked eye with an apparent visual magnitude of +5.49. Based upon an annual parallax shift of $15.15$ as seen from the Earth, it lies at a distance of 111 light years from the Sun. The star is drifting further away with a radial velocity of +15 km/s.

This object is an F-type main-sequence star with a stellar classification of F4 V, where the luminosity class of 'V' indicates it is currently generating energy through hydrogen fusion at its core. It is 2.12 billion years old and is spinning with a projected rotational velocity of 20 km/s. The star has 1.45 times the mass of the Sun and 1.87 times the Sun's radius. It is radiating 5.8 times as much luminosity as the Sun from its photosphere at an effective temperature of 6,606 km/s.
