Orbital bodies are celestial objects that move in a defined path around a larger body due to gravitational forces. These can include planets, moons, asteroids, and comets. For example, the Earth orbits the Sun, while the Moon orbits the Earth. The motion of orbital bodies is governed by the laws of physics, particularly Newton's laws of motion and Kepler's laws of planetary motion. These laws explain how the speed and distance of an orbital body affect its trajectory and stability in space. Understanding these principles helps scientists study the dynamics of our solar system and beyond.
