The Bad Kreuznach observatory, which usually invites visitors to observe the sun on the Kuhberg mountain, has set up the planetary path in the valley of the river Nahe. Models of the sun and the planets form the individual stations of the walk. The walk takes visitors from the sun to the dwarf planet Pluto. At a distance of 5.9 kilometres, the sizes of the planets and the distances between them are arranged at a distance of 1: 1 billion. Along the way there are nine discs on which the planets are shown to scale giving information on size, temperature, orbit. In this way, visitors can "walk" the distances in the solar system and get an idea of the distances between the planets. In addition, detailed information is provided at the individual stations along the way. The view of the charming, quietly rippling Nahe River rounds off the tour.
