Here, only one planet shares the sun with the earth. While the earth remains unchanged, you can modify every possible parameter of the planetary orbit: The orientation in 3D space, the size, the shape, and the planet's position on the orbit. Just play a little bit with the sliders and get a feel for the orbits and the relative speeds. You can also chose the standard planets of our solar system within 6 astronomical units, i.e. up to Jupiter. These planet's parameters are all taken from literature. Then you can activate the trace and watch cool 3 dimensional loops. Comments and recommendations are always welcome. Have fun!
