The Solar System
This is a small series that displays the distances the planets are from the sun on a scale of one meter to a million kilometers.
So every meter you walk is a million kilometers.
Rutherglen's Bottle represents the sun on this scale. Except that it should be about 1.4 meters in diameter not 9 meters.
There is a traditional cache for each planet (even Pluto gets a guernsey!)
When you reach Pluto you have traveled 5.9 billion kilometers.
Enjoy the walk (bike ride, or most likely 4WD).
The Planet
Mercury is the closest planet to the Sun. Like the Earth's Moon it is a grey, barren world covered in a thick layer of dust and heavily scarred with impact craters.
These craters never erode because of the lack of atmosphere. Mercury at times can be seen close to the Sun, just after sunset or just before sunrise. The ancient Greeks believed it to be two separate objects: Apollo in the morning and Hermes in the evening.
