Drag the timeline to inspect an orbit. Bodies and trails follow the selected time.

Place a massless probe at an idealized equilibrium point of two orbiting bodies.

System Point L1–L3 are unstable; L4 and L5 are stable in the idealized model. All bodies remain editable.

Experiment Comparison runs use up to 20,000 steps.
