It is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.87. When seen through a telescope, it can be separated into three stars: two components with magnitudes 5.4 and 6.0 that lie at an angular separation by 1.8″ (as of 1992) and a yellow-hued star of magnitude 7.2 at a separation of 8.6″ (as of 1990).Monks, Neale Go-To Telescopes Under Suburban Skies https://books.google.com/books?id=waO6tUtfblsC&pg=PA56 56 9781441968517 2010 Springer Science & Business Media New York, New York The orbit of the two brighter stars is not known with certainty, but appears to have a period of somewhere around 700 to 900 years.Malkov, O.
