Celestial mechanics is the branch of astronomy that is responsible for studying the movements of celestial bodies. These movements are due to the gravitational effects exerted by some bodies on others. In order to analyze them, the principles of physics that apply in classical mechanics, such as the Law of Universal Gravitation, by Isaac Newton, are used.

Celestial mechanics studies the movement of two bodies, better known as Kepler's problem; the movement of the planets around the sun; the movement of their satellites or the calculation of the orbits of comets and asteroids.

Within celestial mechanics there are two subfields of study: the **Orbital Mechanics**, centered on the orbits of artificial satellites, and the **Moon theory**, dedicated to studying the orbit of the Moon.

Among the main physicists, scientists and astronomers who participated in the evolution of Celestial Mechanics are Isaac Newton, Nicolás Copernicus, Tycho Brahe, Johannes Kepler, Gottfried Leibniz, Pierre-Simon Laplace, Joseph-Louis de Lagrange, Simon Newcomb or Albert Einstein .
