In classical antiquity, the celestial pole was somewhat closer to Beta Ursae Minoris than to Alpha Ursae Minoris, and the entire constellation was taken to indicate the

Since the medieval period, it has become convenient to use Alpha Ursae Minoris (or "Polaris") as the north star, even though it was still several degrees away from the celestial pole. Its New Latin name of "stella polaris" was coined only in the early modern period. The ancient name of the constellation is "Cynosura" (Greek Κυνοσούρα "dog's tail"). The origin of this name is unclear (Ursa Minor being a "dog's tail" would imply that another constellation nearby is "the dog", but no such constellation is known).
