Albireo Information:
Albireo means the "beak of the hen." Albireo is the fifth brightest star in the constellation Cygnus. Although it has the Bayer designation beta, it is fainter than Gamma Cygni, Delta Cygni, and Epsilon Cygni. Albireo appears to the naked eye to be a single star but can be resolved with a telescope into a double star, consisting of a brighter yellow star (actually a binary system of two stars in orbit) and a fainter blue star.
