Here's why:
* Celestial Equator: This is an imaginary line in the sky directly above Earth's equator. It divides the celestial sphere into the Northern and Southern Hemispheres.
* Earth's Rotation: As the Earth rotates on its axis, it creates a circular path in the sky. This path is called the celestial equator.
* Perspective from the Poles: From the poles, the celestial equator would be directly overhead. This means it would be impossible to see it as it would be blended into the sky.
Think of it like this: if you stand at the North Pole, you're looking directly down the Earth's axis, and the celestial equator is perpendicular to that line of sight.
