  Epicycles

I just stumbled across the best graphic illumnation of what an epicycle was (left) - from Sparkleberry springs - this pic is an earth centric view of what the solar system looked like to early stargazers.

Can you imagine what a wrench in our worldview it was to finally apply occam's razor and put the sun at the center of the solar system - and our solar system at the edge of a thin ring of otherwise insignificant stars?

The odd white track is of near earth asteroid 1999RQ36 - which will be passing earth at about 4 million miles away next weekend.
