The "Earth-Moon" mechanical system

One revolution of the Earth is about 24 hours, and one revolution of the Moon around the Earth is 27 days, 7 hours, 43 minutes and 11 seconds, or about 27.32 days.

Behrens developed the "Earth-Moon" system to show the orbits of the stars according to the laws of the universe.

The orbit of the Moon on the dial is one revolution in 28 days and the Earth in the middle is 24 hours.
