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 ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
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]
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.
Epsilon Cygni (ε Cygni, abbreviated Epsilon Cyg, ε Cyg) is binary star in the constellation of Cygnus. With an apparent visual magnitude of 2.48, it is readily visible to the naked eye at night, and is the third-brightest star in the constellation. Based upon parallax measurement, Epsilon Cygni is about 73 light-years distant.
The WGSN approved the name Azelfafage for Pi 1 Cygni on 12 September 2016 and it is now so included in the List of IAU-approved Star Names. [10] For such names relating to members of multiple star systems, and where a component letter is not explicitly listed, the WGSN says that the name should be understood to be attributed to the brightest ...
Gamma Cygni (γ Cygni, abbreviated Gamma Cyg, γ Cyg), officially named Sadr / ˈ s æ d ər /, [11] [12] is a star in the northern constellation of Cygnus, forming the intersection of an asterism of five stars called the Northern Cross.
