Polaris is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Latin. It is the name of HIP 11767 (α UMi, HR 424) in constellation Ursa Minor.
Etymology and History
A Latin adjective meaning "of the pole" (related to the noun polus, "the pole"). Applied as a star name to α UMi in the late 15th and early 16th centuries, it reflects the star's temporary proximity to the north celestial pole.
There was no name for the star in Greek antiquity, just "the one at the tip of the tail [of Ursa Minor]" as Ptolemy put it.
