Planetary path "Heaven on Earth, Rettenegg
The size of the universe is made tangible to the visitor during the hike. For example, it takes the light of the sun about the same time to reach Saturn as it takes a hiker to cover this distance on the planetary path.
The planetary path "Heaven on Earth" Rettenegg - Stuhleck is a scientific - touristic project in cooperation with the Institute for Astronomy of the University of Vienna. On the planetary path, the celestial bodies of the solar system are represented in models in size and distance to each other on a scale of billions on the approximately 7 km long stretch between Rettenegg and Stuhleck.
The arrangement of the classical planetary bodies took place thereby after their position of 5. May of the year 2000.
At the starting pavilion and the locations of the planetary models are boards with descriptions for Earth, Moon, Sun, Mercury, Venus, Mars, the asteroid belt, Jupiter, Saturn, Uranus, Neptune and Pluto. These descriptions additionally provide a link between modern astronomy based on today's worldview and the astronomy of past cultures and eras.
The green signposts with the inscription Planetenweg and the symbol show you the way from the starting pavilion to the Stuhleck.
