🪐 Orbital Resonance Explorer (2D)

Top-down 2D Canvas simulation of orbital resonance: real Kepler's-third-law period-radius relationship, adjustable radius ratio for 2:1, 3:2, 5:2 resonances, live conjunction tracking and libration/circulation of the resonance angle.

⚙ Under the hood

A top-down 2D orbital-mechanics view: two or three bodies circle a central star at real Kepler's-third-law periods. Pick a resonance preset (1:1, 2:1, 3:2, 5:2 or a custom radius ratio) and watch conjunction points repeat in fixed directions when the orbits lock into resonance, or drift when they don't.
