celestial coordinate system

The celestial coordinate system is a way astronomers locate objects in the sky, similar to how we use latitude and longitude on Earth. It uses two main measures: right ascension (like longitude), which indicates an object's position eastward along the celestial equator, and declination (like latitude), which shows how far north or south an object is from the celestial equator. This system enables precise identification of stars, planets, and other celestial objects from our viewpoint on Earth, helping astronomers find and track them across the vast sky.
