Case 7: Earth and Satellite Or Kepler's clock

There is an interesting idea - to create a watch whose face is a kind of satellite orbit with moving sectors, marking the second law of Kepler. See. Drawing and animation!

One video of Kepler clock

It will be good to have this clock here Weil der Stadt – die Keplerstadt im Landkreis Böblingen | Kepler-Museum or here Kepler in Prague
