The Northern Cross is an astronomical asterism in the northern hemisphere of the celestial sphere, corresponding closely with the constellation Cygnus the swan. It is much larger than the Southern Cross and consists of the brightest stars in Cygnus: Deneb , Sadr , Gienah , Delta Cygni and Albireo .
Albireo is the star in the head of the constellation of Cygnus (bottom). β Cygni (Latinised to Beta Cygni) is the system's Bayer designation. The brighter of the two components is designated β¹ Cygni or Beta Cygni A and the fainter β² Cygni or Beta Cygni B. The origin of the star system's traditional name Albireo is unclear.
Theta Cygni (θ Cygni, θ Cyg) is a star in the northern constellation of Cygnus. It has an apparent visual magnitude of 4.5, so it can be seen with the naked eye in sufficiently dark skies . Based upon parallax measurements, it is at a distance of about 59.8 light-years (18.3 parsecs ) from the Earth .
