        tdemo_planets_and_moon.py

Gravitational system simulation using the
approximation method from Feynman-lectures,
p.9-8, using turtlegraphics.

Example: heavy central body, light planet,
very light moon!
Planet has a circular orbit, moon a stable
orbit around the planet.

You can hold the movement temporarily by
pressing the left mouse button with the
mouse over the scrollbar of the canvas.
