Planetary systems are groups of celestial bodies that orbit a star, with planets being the most prominent members of the system. A planetary system typically includes: 1. **Stars**: The central body is usually a star (or stars, in the case of binary or multiple star systems) around which the rest of the system orbits. 2. **Planets**: These are large celestial bodies that orbit the star.
