Chicago, Astronomy & Astrophysics Lines: 13 Xref: watmath net.origins:2430 net.physics:3299 Oooh, excellent point, Jeff! I did the derivation another (simpler) way and got out an Earth-Saturn distance of 4 Saturn radii, which made my approximations invalid, so I did it again solving the quartic (with help from macsyma) and got an Earth-Saturn distance of 49.3 megameters. The radius of Saturn is about 60.3 megameters, so the Earth would have to be down in the clouds somewhere to lower our surface gravity at the sub-Saturn point by 500 cm/sec^2. Of course this won't stop the Velikovskians. They're probably all Capricorns. :-) _____________________________________________________ Matt University crawford@anl-mcs.arpa Crawford of Chicago ihnp4!oddjob!matt Brought to you by Super Global Mega Corp .com
