Each meter on the path corresponds to 10 millions of kilometers in the actual solar system, which means that when you walk quietly the "Sentier planétaire", you are supposed to speed faster than light !
Here, the rings of Saturne are aging fast as in order to be at the right scale, they had to be thin !
Nemorino has an excellent page on a ten times larger Planetary trail in Queckbronn. Given its size, it is advisable to cycle the trail!
Three projects were presented. Cherif Kebbal's project, architect and teaching in the École d'Architecture de Grenoble won as it fulfilled all expectations and included students in its achievement, as part of their end of studies project.
Here, Mars, the red planet is in the foreground.
The project was aimed to build at actual scale our solar system. All distances had to be exact, all sizes to fit to reality and when possible, the surface of each planet had to be represented as we know it now. However there is a 1/90 ratio between distances and sizes of the planets.

The "Sentier planétaire" was realized in 2004 in the campus though the idea began to brew in 1996. The idea came from Manuel Forestini, researcher in the Laboratory of Astrophysique. It is the building of a small scale representation of our solar system.
