A detailed 3D solar system with 8 planets, major moons, Saturn's iconic rings and the asteroid belt. Realistic orbital periods and inclinations bring the cosmic clockwork to life.
Keplerian orbital mechanics with eccentricity, inclination and true anomaly. Moons orbit their parent planets while the whole system moves together.
Click a planet to focus the camera on it. Zoom in to see moons and rings. Watch the orbital periods — Mercury completes many orbits while Neptune barely moves.
The solar system extends far beyond Neptune. The Oort Cloud, a spherical shell of icy bodies, is thought to reach halfway to the nearest star — about 1 light-year from the Sun.
