Real-time astrophysics simulator demonstrating Kepler's planetary laws, eccentric orbits, Hohmann orbital transfer trajectories, gravitational escape velocity, and exoplanet transit photometry.
3D Solar System simulator numerically integrating Kepler three laws and Newton universal gravitation.
Drag to orbit the 3D viewport, select celestial bodies, and adjust simulation time scale.
Satisfies angular momentum conservation under central inverse-square gravitational fields.
Mean Earth-Sun orbital distance, approximately 149.6 million kilometers.
That orbital period squared is proportional to semi-major axis cubed (T² ∝ a³).
