Title: “The Shifting North Star: Unraveling the Mystery“
For centuries, the North Star, also known as Polaris, has guided navigators and stargazers as a steadfast reference point in the northern sky. But did you know that the North Star changes from time to time?
This phenomenon is due to the Earth’s axial precession, a slow wobble in its rotation that takes approximately 26,000 years to complete one cycle. As our planet wobbles, the direction in which its axis points changes. Consequently, the North Star position shifts over time.
Around 3000 BCE, the star Thuban served as the North Star. In approximately 12,000 years, Vega will take on this role.
Understanding the changing North Star offers a captivating glimpse into the Earth’s celestial dance, reminding us of the ever-evolving relationship between our planet and the cosmos.
