Philip M From philip madsen Thu Nov 15 22:17:53 2007 Now there is a thought what star trail would you get if you had a camera on the north pole of the moon, doing its alleged 28 day spin. I haven't checked it carefully but as the Moon is rotating very roughly in 25 hours (geocentric model) and the stars in a little less than 24, I'd say it will be the same as in the heliocentric model where it will be a bit more that 27 days. Important point here though. I couldn't find data but it's an odds on bet that Polaris will not be the focus. Paul D Make the switch to the world's best email.
