WHAT IS THIS?
A real-time Solar System simulation using Kepler's laws. All 8 planets orbit the Sun with accurate relative periods and distances.
WHAT'S IT FOR?
Visualise orbital mechanics — why inner planets orbit faster, how gravity keeps everything in sync, and the vast scale differences in our Solar System.

THE SCIENCE
Period² ∝ Distance³ (Kepler's 3rd Law). Mercury orbits 4× faster than Earth. Neptune takes 165 Earth years per orbit.
