Gravity Sandbox

Pick a mass, then click empty space to drop a body — or drag and release to fling it into orbit. Click an existing body to retarget its velocity (drag to aim, or click without dragging to stop it). Everything pulls on everything else; bodies that collide merge. Tip: drop one heavy "sun," then lower the mass and fling light planets around it.

Click a body: retarget / stop it · Right-click a body: delete · Right-drag: pan · Scroll / pinch: zoom
