The visible components, A and B, have an angular separation of 9.8 arc seconds and share a common proper motion. Their presumed orbital period is estimated as 4,400 years. Component A was first identified as a single-lined spectroscopic binary by Adams et al. (1924) at the Mount Wilson Observatory. It has an orbital period of 21.2 days with an eccentricity of 0.60.[3] The Aab pair have an angular separation of 6 mas and a combined stellar classification of F4 V Fe−0.4,[4] matching an F-type main-sequence star with a mild underabundance of iron. Magnitude 10.92 component B is likewise a single-lined spectroscopic binary, having an orbital period of 659.9 days and an eccentricity of 0.70. The separation of Bab is 45 mas,[3] and their spectrum matches a red dwarf class of M3 V.[3]
