Kepler-9

This simulation shows the Kepler-9 planetary system, as detailed in the Wikipedia article at:

https://en.wikipedia.org/wiki/Kepler-9

If you set the simulation running, you can watch how it evolves, and see how the orbital elements of the three planets slowly change with the passage of time. Since different computers run at different speeds, you may need to edit the evolution time step to get the simulation to run at an acceptable rate.
