Gienah cygni
Epsilon Cygni
Names For This Star
Gienah derives from the Arabic Al Janah meaning "The Wing." The star should probably be called "Gienah Cygni" to distinguish it from the Gienah in Corvus.
Description of the Star
Gienah Cygni is a cool, orange K0-III giant star 40 times as luminous as the sun. The spectral type implies a temperature of perhaps 4500 K, a mass more than 4 times that of the sun and a radius maybe 16 times greater.
Gienah has a dim 13th magnitude companion designated Gienah C lying 78 seconds of arc from the A component, corresponding to a projected distance of 1700 AU. (The B component seems not to be physically associated with the system; it is merely a background star that appears at a small angular separation from A.)
