Astronomical coordinate systems are frameworks used by astronomers to specify the positions of celestial objects in the sky. Since the Earth is constantly moving (rotating on its axis and orbiting the Sun), a consistent system is necessary to accurately describe the locations of stars, planets, and other celestial bodies. There are several main types of astronomical coordinate systems, including: 1. **Equatorial Coordinate System**: - This is the most commonly used system for locating stars and celestial objects.
