Kepler's laws: Explore the orbits of other worlds

Welcome to Kepler's Laws of planetary motion simulation. In this simulation, you will learn how the planets in a Solar system orbit around their Sun and, more generally, how objects move in a system of attractive central forces.

Kepler's laws apply to every system where comparatively lighter bodies (in the Solar system, the planets) orbit a much heavier body (in the Solar system, the Sun).

Following is a list of all the relevant theory pages to boost your learning. You may consult them at any time.
