A binary star consisting of two stars with magnitudes of 4.2 and 6 has a mutual orbital period of 87 years. The orbital path has such a spatial position that the apparent angular separation of the two stars significantly changes during the orbital period. The smallest separation (1.5") was reached by both stars in 1989 and 1990. At the turn of the millennium, their separation increased to 3.9", which could be observed even with a telescope with a 5 cm diameter objective. In 2005, the distance increased to 5". The largest separation of 6.8" will be reached by both stars in 2024.
