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.
