🧪 Solar System Orbits (3D)

The 2D original animates eight planets on a flat canvas: each planet's angle is computed as (time / period) * Math.PI * 2 using its real relative orbital period in Earth days (Mercury 88 through Neptune 60190), positioned at cos(angle) * distance * viewScale / sin(angle) * distance * viewScale around a fixed Sun, with a Kepler-law sidebar, an Earth-angle readout and a Saturn ring drawn separately at the same angle formula. This 3D companion keeps every one of those numbers and that exact formula — the same eight periods, the same relative distances, the same per-frame time += timeSpeed increment — and runs it on a real sphere-orbiting-sphere Three.js scene: each planet is a lit 3D mesh moving along a true circular path in the X/Z plane around an emissive Sun with its own point light, Saturn keeps its ring mesh locked to its live 3D position, and the camera is a genuine free-orbiting perspective camera (drag to rotate, scroll to zoom) rather than a flat top-down view.
