Celestial points are specific locations in the sky used in astronomy to help locate stars, planets, and other celestial objects. The most important celestial points include the North Celestial Pole and the South Celestial Pole, which are the points in the sky directly above the Earth's poles. These points are essential for navigation and understanding the movement of celestial bodies. Another key celestial point is the Celestial Equator, an imaginary line that divides the sky into the northern and southern celestial hemispheres. It is directly above the Earth's equator and helps astronomers map the positions of stars and constellations. Understanding these points is crucial for studying the universe.
