ξ Cygni (Latinised as Xi Cygni) is a spectroscopic binary star in the constellation Cygnus, made up of a K-type supergiant star (primary) and an A-type star (secondary). Its apparent magnitude is 3.73, making it readily visible to the naked eye , and it is located around 350 parsecs (1,100 ly) away.
The fifth star in Cygnus above magnitude 3 is Aljanah, [23] designated ε Cygni. It is an orange-hued giant star of magnitude 2.5, 72 light-years from Earth. [25] [26] There are several other dimmer double and binary stars in Cygnus. μ Cygni is a binary star with an optical tertiary component. The binary system has a period of 790 years and is ...

Nu Cygni, Latinized from ν Cygni, is a binary star [8] system in the constellation Cygnus. Its apparent magnitude is 3.94 [ 2 ] and it is approximately 374 light years away based on parallax. [ 1 ] The brighter component is a magnitude 4.07 A-type giant star with a stellar classification of A0III n, [ 3 ] where the 'n' indicates broad ...
Deneb is the brighest star in the constellation of Cygnus (top) α Cygni (Latinised to Alpha Cygni) is the star's designation given by Johann Bayer in 1603. The traditional name Deneb is derived from the Arabic word for "tail", from the phrase ذنب الدجاجة Dhanab al-Dajājah, or "tail of the hen". [12]
ψ Cygni, Latinised as Psi Cygni, is a triple star [3] system in the constellation called Cygnus. With a combined apparent visual magnitude of 4.92, [ 2 ] it is visible to the naked eye. As of 2002, the inner pair, components Aa and Ab, had an angular separation of 0.10 arc seconds along a position angle of 77.6°. [ 12 ]
NML Cygni or V1489 Cygni (abbreviated to NML Cyg or V1489 Cyg) is a red hypergiant [4] or red supergiant (RSG) in the constellation Cygnus.It is possibly one of the largest known stars currently known, and is also possibly one of the most luminous and massive cool hypergiants, as well as one of the most luminous stars in the Milky Way.
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 .
