Alpha Ursae Minoris, "Polaris", (once 
called "Alracubba" by medieval Arabs),
is the current pole star. It is both a 
variable and a double star of 18 
seconds separation. Its closest 
approach to the pole will be in 
2102 A.D. Observing the "motion" of 
the stars, you'll see them "revolve" 
around Polaris.
