Schneller als das Licht / Faster than the speed of light
This cache link my hobbies geocaching and astronomy. The multi-cache follows the "Planetenweg" (Path of the planets), which was built by the "Westfälische Volkssternwarte und Planetarium Recklinghausen" (observatory Recklinghausen). The "Planetenweg" displays the sizes and distances in our solar system in the scale of 1:3 billion.
Each station on the "Planetenweg" consists of an informationplate on a steelcolumn. Some data to the planet is written on the plate. The planet is displayed on the plate in the right scale. More information about the observatory can be found at www.sternwarte-recklinghausen.de . The observatory has an very interesting program. Worth a visit for fans of astronomy.

Walk to the observatory at N51°37.427, E7°10.837. The informationdisplay at N51°37.431, E7°10.849 inform you about all aktivities of the observatory. At the door of the observatory there is mostly a small programguide to take with you.
Startpoint: Sun (N51°37.404 E7°10.849)
The sun stands below the observatory.
The sun is the source of most life on earth. At this point the light of the sun starts its voyage. We have the unique opportunity to travel faster than the light through our solar system.
Task: The steelcolumn of the sun stands in the middle of a star. How many points has this star? A=
Planet 1: Mercury (N51°37.399, E7°10.857)
The Mercury is still very close to the observatory.
distance form the sun: 58 Mio km
traveltime of light: 3.22 minutes
Task: What is standing direct next to the steelcolumn of the Mercury?
street lamp: B = 3
bank: B = 5
big tree: B = 7
nothing: B = 9
Planet 2: Venus (N51°37.402, E7°10.872)
The Venus is close to the observatory too.
distance form the sun: 108 Mio km
traveltime of light: 6 minutes

Task: What colour has the fence between path and playground?
blue: E = 3
green: E = 5
white: E = 7
silver-painted: E = 9
grey: E = 9
Planet 5: Jupiter (N51°37.287, E7°10.978)
We leave the inner planets behind and turn towards the outer planets. The distances grow. The Jupiter is at the entrance of the animal park.
distance form the sun: 779 Mio km
traveltime of light: 43,27 minutes
Task: A big coniferous tree is standing next to Jupiter. There is a small sign of metal with a number on the stem. F = number - 233

The city of Recklinghausen invites to rest a bit. There are a lot of cafes, restaurants and shops. For a short break I suggest the snack bar at the Karstadt-Building (market-place). They have very good "holländische" fried potatoes (sorry no coordinates, the gps-reception is very bad because of the high buildings).
