The VSOP model, which stands for "Variations Séculaires des Orbites Planétaires" (French for "Secular Variations of Planetary Orbits"), is a mathematical model used in astronomy and celestial mechanics to describe the positions and movements of the planets in the solar system. It was developed by the French mathematician and astronomer Pierre-Simon Laplace in the early 19th century and has been refined over time.
