That ugly blob over there on the right is Jupiter. Well, Jupiter as I built it for school when I was eight in 1974. I found it recently in my mom’s house but couldn’t find the rest of the solar system, even another gas giant, to go with it. I distinctly remember getting the color scheme from the Pioneer 10 fly-by which I saw live on a broadcast at the San Francisco Exploratorium. Anyway, back at school I made a scale model solar system for class and while I couldn’t quite get the distance scale correct (Pluto would have been somewhere out in Kern County), I got the planet diameters down. Even got my photo in the local newspaper in their feature on my class. Some kids play with scale model trains, others build planets…
Couple years back I took a picture of part of the scale solar system in downtown Ithaca, New York.
What’s the point of all this? Some kids and scientists in the UK are building a scale solar system of their own (BBC news story). A little Googling turns up a meta-directory of scale solar systems.
