Orbit

Concept

Gravitational bodies in space. Each attracts the others. Simple rules create complex dances — stable orbits, chaotic spirals, collisions, escapes.

Interaction

Click to spawn a body. Click and drag to give it initial velocity. Watch them interact. Press C to clear. Press R for a random system.

Physics

F = G(m₁m₂)/r². Newton's law of universal gravitation. No friction, no mercy.
