Human Orrery

A nice idea was demonstrated by Armagh Planetarium at the EPO session on Monday evening. They have recently built a large-scale orrery from stainless steel plates. Each plate represents the position of a terrestrial planet, Saturn, Jupiter and even objects such as Encke at 16 day time intervals. The idea is that, if you get a big group of people, you can mark out the solar system as it is now (to within 16 days) and see how it will change as time goes by. You just get the people to move foward a disc at a time. This lets you work out where the planets would be in the night sky, explore Kepler's Laws and do plenty of other things that I can't remember now. What I do remember is that it looked like fun.

I'll add a link when I can find one.
