Here's why:
* Earth's Rotation: The Earth rotates on its axis once every 24 hours. This rotation causes the stars to appear to move across the sky.
* Celestial Poles: The celestial poles are points in the sky directly above Earth's geographic poles. Due to Earth's rotation, stars appear to rotate around these poles.
* Hemisphere: If you are in the Northern Hemisphere, you will see stars circling around the north celestial pole. If you are in the Southern Hemisphere, you will see stars circling around the south celestial pole.
Important Note: This is an apparent motion. The stars are actually very far away and do not physically rotate around the poles. It's simply our perspective from Earth's rotating frame of reference.
