It is dimly visible to the naked eye with an apparent visual magnitude of 5.64. Parallax measurements by Hipparcos put the system approximately away. It is drifting closer with a radial velocity of −10 km/s.
The Hipparcos satellite mission derived a orbit on the basis of its motion caused by an unseen companion. The visible component is an A-type subgiant or F-type giant star with an effective temperature of about 6,900 K. It has an absolute magnitude of 2.56, a mass of, and a radius of.
