While playing with gear design again, I thought I could add a second row of planets (or are these moons?) to get some interesting behavior:
- If you lock the ring in position and rotate the sun gear, the planets rotate in the other direction around the sun.
- If you hold the sun gear steady and rotate the ring, the planets move in the same direction as the ring, but faster than the ring!
Also try this little hand crank for some more fun →
