* Precession: The Earth's axis slowly wobbles like a spinning top, a phenomenon called precession. This wobble takes about 26,000 years to complete a full cycle.
* Shifting North Star: Because of precession, the star that appears closest to the North Celestial Pole (our "North Star") changes over time. Currently, Polaris is our North Star. In 14,000 years, due to precession, the star Vega will be our North Star.
Important Note: While Vega will be the closest to the North Celestial Pole in 14,000 years, it won't be *perfectly* aligned like Polaris is today. The North Star's position will still be slightly off-center from the true North.
