Polaris--(α Ursae Minoris, α UMi, commonly the North Star or Pole Star) is the brightest star in the constellation Ursa Minor. It is very close to the north celestial pole, making it the current northern pole star. The revised Hipparcos parallax gives a distance to Polaris of about 433 light-years (133 parsecs) while calculations by other methods derive distances around 30% closer.
Precession Sky Chart: The 26,000-year precession cycle causes the north celestial pole to move counter-clockwise relative to the backdrop stars. Whichever star is closest to the north celestial pole is the Pole Star.
