It is visible to the naked eye as a dim, yellow-white hued star with a combined apparent visual magnitude of 5.63. Based upon parallax measurements, it is located around 159 light years away from the Sun. The system is receding from the Earth with a heliocentric radial velocity of +12.9 km/s. The pair orbit each other with a period of approximately 325 years and an eccentricity of 0.59. The semimajor axis of the orbit has an angular size of 1.39 arcsecond. The magnitude 5.92 primary, designated component A, is an aging F-type subgiant star with a stellar classification of F8 IV. The secondary star, component B, is a magnitude 7.95 F-type main-sequence star with a stellar classification of F9 V. There is a magnitude 13.5 visual companion, designated component C, at an angular separation of 95.30 arcsecond along a position angle of 150°, as of 2001.
