Mécanique Céleste

Mécanique Céleste, or Celestial Mechanics, is the branch of astronomy that studies the motions of planets, moons, and other objects in space based on the laws of physics, particularly gravity. It uses mathematical models to understand and predict their paths and interactions over time. The field builds on Newton’s laws of motion and gravitation, providing precise calculations for orbital trajectories, explaining phenomena like eclipses or planetary eclipses, and underpinning space exploration. Essentially, it is the science of understanding how celestial bodies move and influence each other in the universe.
