Zeta Draconis (ζ Draconis, abbreviated Zet Dra, ζ Dra) is a binary star in the northern circumpolar constellation of Draco. With an apparent visual magnitude of +3.17, it is the fifth-brightest member of this generally faint constellation. Its distance from the Sun has been measured using the parallax technique, yielding an estimate of roughly . The two components are designated Zeta Draconis A (formally named Aldhibah , after the traditional name of the system) and B. Nomenclature ζ Draconis (Latinised to Zeta Draconis) is the system's Bayer designation. The designations of the two components as Zeta Draconis A and B derives from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU). Zeta Draconis has the old Arabic name الذئب al-dhiʼb "the wolf" or "the hyena", given in its feminine form "Al Dhiʼbah" (ذئبة) in Allen (1899) (though he mistranslated it as plural "hyenas", which would be الضباع al-ḍibāʽ). It shares the dual form of the name, الذئبين al-dhiʼbayn, with Eta Draconis. It is also known as Nodus III (Third Knot, the knot being a loop in the tail of Draco). In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog 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 Aldhibah for the component Zeta Draconis A on 5 September 2017. It also approved the name Athebyne for Eta Draconis A on the same date. Both are now so included in the List of IAU-approved Star Names. Zeta Draconis is mentioned in Hindu texts as Tara who was a celestial goddess married to Lord Brhaspati. A divine epic was played out in the night sky when Lord Chandra, the moon, lusted after and abducted Tara, the blue pole star of Brhaspati, the planet Jupiter. By the completion of the epic Tara gives birth to Lord Budha, or Mercury. In Chinese, (), meaning Left Wall of Purple Forbidden Enclosure, refers to an asterism consisting of Zeta Draconis, Iota Draconis, Eta Draconis, Theta Draconis, Upsilon Draconis, 73 Draconis, Gamma Cephei and 23 Cassiopeiae. Consequently, the Chinese name for Zeta Draconis itself is (, ), representing (), meaning The First Minister. 上弼 (Shǎngbì) is westernized into Shang Pih by R.H. Allen with meaning "the Higher Minister". Properties Zeta Draconis A is a
