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
Earth is unique, the only place we know in the Solar System and galaxy that supports life. It lies within the Sun's 'habitable zone' with liquid water on its surface and with life-supporting concentrations and amounts of chemicals.
The core of iron is covered by a thick mantle of liquid rock. Continents and oceans float on the thin outer crust of solid rock. The atmosphere is 78% nitrogen, 21% oxygen, a little carbon dioxide and other gases.
The Moon is about one quarter the diameter of the Earth. Scientists believe it was formed after an object the size of Mars collided with the Earth when it was very young.
