Northern polar starIts story
Yildun is a small white star in the tail of Ursa Minor, very close to Polaris in the asterism's outline. Its name, drawn from the Turkish «yıldız», simply means «star» — a rare case among stellar names of mostly Arabic origin. At 172 light-years, it seems almost to stand guard over the celestial North Pole, that motionless point around which the whole northern sky appears to wheel.
