Ugears 3D Wooden Mechanical Puzzle Tellurium

About the orbits of the celestial spheres! Telluria kit made of plywood. Discover the magic of Renaissance astronomy and the revolutionary work of Nicolaus Copernicus while building a sophisticated mechanical model first developed by the Dutch mathematician Christiaan Huygens. It depicts the mutual position of the Earth, Moon and Sun in relation to the constellations of the zodiac, but also the inclination of the Earth's axis and the plane of rotation of the moon. You can easily set the celestial bodies in motion by turning the crank, which is in the same ratio to the rotation of the Earth model, so you have plenty of time for the whole show. You can follow all phases of the mechanism in detail, think about them and clearly demonstrate them to your friends or children. The model can of course be set according to the calendar and observe all the relationships shown exactly as they are happening, always with one turn of the crank per day. Tellurium is a great gift for anyone who wants to discover natural phenomena, whether it's a young student, an enthusiastic astronomer, or just a curious fan of mechanics.
