Precession changes the pole star. Earth's axis has a little wobble in it, so over 26,000 years the axis points to a slightly different area of sky. During that time the north pole star also changes. In 12,000 years it will point towards Vega. Mona Evans, "Ecliptic and Equinoxes" http://www.bellaonline.com/articles/art20530.asp

Perseid meteor and ISS, August 13, 2012. (Photo: Martin Popek) The immediately obvious thing is the star trails, but the horizontal line cutting across the trails is the International Space Station going overhead. There is a bright Perseid on the left hand side of the picture. The Perseid meteors are tiny fragments of the debris of comet 109P/Swift-Tuttle. ©Mona Evans, "Meteor Shower - the Perseids" http://www.bellaonline.com/articles/art27461.
