Orbital playground

Launch a satellite around a fixed central mass and explore its orbit in three dimensions.

Drag to rotate, scroll or pinch to zoom. Try an orbit preset, then change its launch speed and inclination. Arrow keys rotate the view.

Newtonian gravity with unit GM and launch radius. The central mass stays fixed. The dashed line predicts the orbit; the arrow shows velocity. Planet appearance is illustrative. Three.js · OrbitControls
