A Northern Hemisphere constellation (known also as the Northern Cross) in the Milky Way, directly east of the Lyre, and nearly on the same meridian as the Dolphin. Seen from May to December. Its brightest star, Deneb, is in the tail of the Swan, and always above the horizon in England. One named 61 Cygni (a small variable star in this constellation and almost invisible to the naked eye), was the first to have its distance from the Earth determined - 50 billion miles.
