It's by Dava Sobell. There are bits of good info in this too.I've never "crammed"https://community.betfair.com/chit_chat/go/thread/view/94038/23442150/a-favour-required-please---of-a-quiz-nature?post_id=418527378#418527378I got a Talking book from the Library, simply called 'The Planets' - I wish I had a walkman (on cassette, not CD), I Played the 1st 3 sides so far - there are 12 sides.

I'll let Oval explain :)I don't know the AU, but it's about 67,000 miles.https://community.betfair.com/chit_chat/go/thread/view/94038/23442150/a-favour-required-please---of-a-quiz-nature?post_id=418527126#418527126I think we have a sort of average rotation and spin, PW - the inner planets spin really slowly, but revolve around the sun in quick time, ...... and....
