Grein, Oberösterreich, Österreich
On a scale of exactly 1:2.8 billion, our entire solar system stretches along the Danube quay from the Greinerbach stream almost as far as the Danube bridge.
The idea and design came from the Greiner physicist Dr Werner Riegler, who has been researching the smallest particles in our cosmos at the LHC Cern particle accelerator in Geneva for years.
To explore the solar system in detail, it is best to start after the Greinerbach Bridge with the sun, which is shown with a precise description at the beginning with a diameter of half a metre. It continues with Mercury, Venus, Earth and Mars. After the asteroid belt comes Jupiter, which has had its place opposite the Schörgi confectionery for a year now. Saturn can then be discovered a little further away at the corner of Esperantoplatz and the campsite. You then have to walk or cycle a little way to Uranus, which is located at the end of the wall below the Hofer car park. You then have to walk or cycle to Neptune 50 metres before the Danube bridge on the cycle path. After you have studied all the planets in detail, take a detailed look back to Grein as far as the sun at Greinerbach and you will get a good feeling for the vastness and distances of our solar system.
All the planets are shown in the correct proportions.
