Your own planetary sandbox.
MISSION
Select objects by clicking or with the object list. In paused editing, drag to move, arrow keys move the selected object, Shift gives smaller steps. Space runs or pauses. Delete removes the selected object. Control Z undoes an edit. Tab cycles objects; Escape cancels placement. Use numeric properties for exact positions. Wheel zooms; drag empty space to pan.
YOUR GRAVITATIONAL INVESTIGATION
Use probes for field values; vectors show directions.
Graph windows stay linked to the scene. Click a time graph to replay that instant, or a spatial graph to inspect its position.
