Based on a 1:300,000,000 scale, each cache contains a planet to the same scale - or 61% here, to fit the rings in the cache (much smaller on the lid) - and is sited at the correct distance from the globe. Thus, if you could see it from the Earth cache, the golden globe would appear to be 1/2 of a degree across, just as the sun appears from the Earth.
Saturn is the second largest planet in our solar system and is shown in the box a little smaller than scale size, so it'd fit! It's less dense on average than water, meaning Saturn (the planet, as well as the cache!) would float if you could find a bath big enough to put it in (the planet, not the cache. Please don't put this cache in your bath.)
For ease of access, look for a well hidden footpath at Nobels Farm. It starts on your right at the end of a fenceline if doing the caches in number order. Seeing ' Private Keep Out' signs? You've missed a turning somewhere. You can walk on and take the sharp-right path, which brings you back, lower down the hillside. Please don't ignore the Private Keep Out signs!
