Xi Draconis

Xi Draconis (ξ Draconis, abbreviated Xi Dra, ξ Dra) is a double or binary star in the northern circumpolar constellation of Draco. It has an apparent visual magnitude of 3.75. Based upon parallax measurements, it is located at a distance of from the Sun. At this distance, the apparent magnitude is diminished by 0.03 from extinction caused by intervening gas and dust.
The two components are designated Xi Draconis A (officially named Grumium , a traditional name for the system) and B.
Nomenclature.
"ξ Draconis" (Latinised to "Xi Draconis") is the system's Bayer designation. The designations of the two components as "Xi Draconis A" and "B" derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
It bore the traditional names "Grumium". This is a graphic corruption of the Latin "Grunnum" 'snout', as Ptolemy had described this star as being on the jawbone of the dragon. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalogue and standardize proper names for stars. The WGSN decided to attribute proper names to individual stars rather than entire multiple systems. It approved the name "Grumium" for the component Xi Draconis A on 12 September 2016 and it is now so included in the List of IAU-approved Star Names.
This star was also known as "Nodus I" or "Nodus Primus". Along with Beta Draconis (Rastaban), Gamma Draconis (Eltanin), Mu Draconis (Erakis) and Nu Draconis (Kuma), it was one of "Al ʽAwāyd" "the Mother Camels", which were later known as the "Quinque Dromedarii". 
In Chinese, (), meaning "Celestial Flail", refers to an asterism consisting of Xi Draconis, Nu Draconis, Beta Draconis, Gamma Draconis and Iota Herculis. Consequently, the Chinese name for Xi Draconis itself is (, ).
Namesake.
USS Grumium (AK-112) was a United States Navy Crater class cargo ship named after the star.
Properties.
Xi Draconis A is of spectral class K2-III. The possible companion, Xi Draconis B, is a 16th magnitude star 316 arcseconds away but, most likely, the pairing is just a line-of-sight coincidence.
