NotesThe name Gienah means 'wing', and Cygnus the Swan is the not the only bird-constellation to have a star with this name. The other is in Corvus, the Crow, whose Gamma star is also named Gienah. The two are sometimes designated Gienah Cygni and Gienah Corvi to avoid confusion.

One of two stars (the other being Delta Cygni) that together define the outstretched wings of Cygnus the Swan. Gienah is a triple star almost eighty light years from the Sun.
