Celestial Mechanics is the branch of astronomy that deals with the motions and gravitational interactions of celestial objects. It helps us understand how planets, moons, and other bodies move in space, influenced by forces like gravity. This field is essential for predicting the orbits of satellites and understanding phenomena such as eclipses and tides. By applying the laws of physics, particularly Newton's Laws and Kepler's Laws, celestial mechanics allows scientists to calculate the trajectories of objects in space. This knowledge is crucial for space exploration, satellite deployment, and even understanding the long-term stability of planetary systems.
