Orbital systems refer to the arrangements and movements of celestial bodies, such as planets, moons, and artificial satellites, as they travel around a central object, typically a star like the Sun. These systems are governed by the laws of physics, particularly Newton's laws of motion and Kepler's laws of planetary motion, which describe how these bodies interact through gravitational forces. In addition to natural celestial bodies, orbital systems also include human-made objects, such as satellites and space stations, which are placed in specific orbits for purposes like communication, weather monitoring, and scientific research. Understanding these systems is crucial for space exploration and navigation.
