The North and South Celestial Poles are the two points where the Earth’s axis of rotation, extended into space, intersects the celestial sphere.
- North Celestial Pole: This is the point in the sky that is directly above the Earth’s North Pole. It lies near the star Polaris (the North Star), which is used to indicate the direction of true north in the Northern Hemisphere. In the sky, it is located about 1 degree away from Polaris, making it a useful reference point for navigation and star tracking.
- South Celestial Pole: This is the point in the sky directly above the Earth’s South Pole. It does not have a prominent star like Polaris to mark its location, so it is harder to find visually. The Southern Cross constellation is often used to locate the South Celestial Pole, as its stars point toward it.
