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
Nepture is a cold distant gas giant. Through a telescope it is bluer than Uranus because it has more methane.
Giant storms whirl through its atmosphere with the fastest winds recorded in the Solar System, up to 2,400km/hr. One storm, nearly as large as Earth, circles the planet every 18 hours.
In 1989 the Voyager 2 spacecraft discovered eleven small moons and a faint ring system.
Triton is the largest moon (2,700km in diameter) and the coldest moon in the Solar System. Geysers of nitrogen spew from its surface.
