The `x` in the left pane is the mathematical origin; the `x` is the center of mass of the system.

Click "Start/Stop Animation" to run the simulation. When animation is stopped, click and drag planets or the tips of their velocity vectors to change their initial position or velocity. Click and drag the shape sphere to view from different angles.
