PLANÉTAIRE DE GRESSWILLER
A global is a mobile mechanical set that represents all or part of the Solar System, with true printed movements to the reality of aspires and celestial mechanics, the Earth taking a turn in a little less than 24 h, the Moon a round around the Earth in just over 27 days, etc. A Gresswiller, to 30 About 0 km west of Strasbourg, at the center of the multi-purpose classroom of the school group of the commune, is hiding a true 9 m in diameter: a planetary built by Michel Rohr, a passionate person in the pure sense who took almost 4 years to realize this masterpiece! 10,000 hours of work to design this mechanical set without any electronics, using a complex game of tringles and gables, with a surprising water engine! The planet thus automatically replicates the rotation and revolution of the Earth and the Moon, the movement of Mercury and Venus, and manually the movement of Mars, Jupiter, Saturn, Uranus, Neptune and Pluton, these latter journeys being for some extremely slow (Pluton takes 248 years to tour the Sun in particular!). In the room, other teaching tools are to be admired, such as a clock to generate the earth's illumination zones according to hours and dates (ideal for understanding the season mechanism). The visit completed, we remain without a voice in front of such a book and the patience it took to realize it!
