Albireo is a beautiful gold and blue double star in the constellation Cygnus. It is still unknown if Albireo is a gravitationally bound binary system or simply a chance alignment optical double. At a distance of 380 light-years, and with a separation of 35 arcsec, the possible orbital period is at least 75,000 years. Given this long orbital period, it will probably take several hundred more years to determine the nature of this double.
