celestial mechanics and dynamical systems

Celestial mechanics is the study of how celestial bodies—like planets, moons, and stars—move and interact under gravity. It uses physics and mathematical equations to predict their paths and behaviors over time. Dynamical systems is a broader field that explores how systems evolve according to specific rules, whether they’re planets orbiting or other complex processes. Together, these fields help us understand and forecast the motion of objects in space, revealing patterns, stability, and chaos in cosmic motions without assuming any prior knowledge beyond basic physics.
