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.						:-)
