About This Product
Turning the crank slowly shows Mercury and Venus completing orbits while the gas giants barely move, a direct picture of how orbital period grows with distance. Lining up Earth and Mars with the Sun and cranking on until Earth overtakes Mars helps explain apparent retrograde motion, and the figures on the base dial turn the demonstration into calculation work on orbits.
Frequently Asked Questions
How are the planets moved on the Solar System Working Model?
A manual handle drives a concentric gear train, so turning it moves all 8 planets at once at different speeds.
What is shown on the base dial?
Astronomical units, orbital durations in Earth days and the zodiac constellations.
