Celestial mechanics is the branch of astronomy and physics that deals with the motion of objects in space, such as planets, moons, stars, and other celestial bodies. This field of study focuses on understanding the gravitational forces and other interactions that govern the movements of these celestial objects, as well as predicting their future positions and trajectories. Celestial mechanics plays a crucial role in space exploration, satellite orbits, and navigation systems, as well as in understanding the formation and evolution of the solar system and other planetary systems. Researchers in this field use mathematical models and computer simulations to study the dynamics of celestial bodies and their interactions with each other, as well as with other forces in the universe.
