Solar System — N-body gravitation with procedural GPU shaders

Scale

Bodies are drawn far larger than life. Orbits and physics are always true to scale.

Asteroid belt

Every asteroid's position is solved on the GPU from a fixed orbit, so the population below is free to change. Ceres, Vesta, Pallas and Hygiea are separate — fully simulated, and clickable.

Velocity-Verlet is symplectic, so the energy error oscillates within a bound instead of accumulating.
