A long walk

About 5900 million km actually, but we caught the train back so we didn't have to walk both ways.
This is the last week of "Our place in Space" sculpture trail where the sun and planets are represented at a scale of 591million to 1, meaning the Sun is 2.35m diameter, the earth is 2.2cm and little Pluto 8.5km away is a mere 4mm.
The inner four planets are only 350m from the sun, the outer planets really are well spaced out!!!!
The extras show the beginning of the trail on Midsummer Common and the end at Waterbeach.
