Thuban
Thuban is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Arabic. It is the name of HIP68756 (α Dra, HR 5291) in constellation Dra.
Etymology and History
The formation of this name begins with the sci-A name for γ Dra: ra's al-tinnin, "the Serpent's Head." In medieval times this was transliterated into Latin as raztaben, rahtaben, razcaben, and several other corruptions (eventually leading to the name for β Dra). By Renaissance times the form Rastaben had appeared, and this name was erroneously attributed, in its last part, to the Arabic word thu'ban, "serpent", rather than to al-tinnin (subsequently thu<ban was wrongly regarded as a sci-A name for the constellation Draco). Finally in recent times, the erroneous word, written as "Thuban," was applied as a star name to α Dra.
