A world premiere: the first ever fully functional cardboard orrery!
It demonstrates the movements of Mercury, Venus, Earth and Moon around the
Sun. One turn of the crank represents one week and shows the relative movements
of the heavenly bodies accurately. The 4.5 cm measuring illuminated sun in the
centre helps demonstrating the seasons, phases of Moon and Venus, eclipses, and
much more. A fantastic kit that never fails to impress!
Kit includes axles, magnets, pulley belts, planets, bearings, and LED
