The Copernicus Planetarium - AstroMedia
Pre-cut cardboard kit for a mechanical planetary model that shows the seasons, moon phases, eclipses and the movements of Earth, Moon, Venus and Mercury in approximate proportion to their orbital periods.
It shows the movements of the inner planets Mercury and Venus as well as the moon and the earth, whereby the latter rotates around its oblique and always equally aligned axis. One turn of the crank on the gear made of rubber belts and grooved wheels corresponds to the course of a week. In the process, it produces six different simultaneous movements, which are in approximate proportion to the actual rotation times. Many celestial processes can be explained in this way from the Copernican (heliocentric) point of view, e.g. the wandering of the sun through the zodiac or the conjunctions of Mercury and Venus with each other and with the sun.
The sun with bright LED illumination shows in the dark room not only the change of seasons, but also the emergence of the moon phases, the eclipses and the crescent phases of Venus.
Here are some customer videos.

Swallowing hazard:
Magnets can be swallowed and cause serious injuries to the body. Keep out of the
reach of children under 12 years of age!
Health risk:
People with pacemakers or other medical devices should keep away from magnets!
Risk for electronic devices:
Strong magnetic fields can damage electronic devices, data storage devices (e.g.
credit cards) and mechanical components or render them unusable. Store magnets
at a safe distance.
Danger of crushing:
Due to their strong attraction, magnets can pinch skin or fingers and cause crushing
or bruising.
Danger of breakage and splintering:
Magnets are brittle and can break into sharp-edged fragments in the event of a
collision, which poses a risk of injury to skin and eyes.
Danger from dust formation:
Grinding, drilling or cutting magnets creates dust that can be self-flammable when it
comes into contact with oxygen and is harmful to health. Mechanical processing
should be avoided!
Dispose of magnets in accordance with local disposal regulations.
