Abstract

An account is given of the various considerations leading to the 10 to the 8th year stability model adopted by Project LONGSTOP for the outer planets and then, on the basis of the expertise thus gained, for the satellites of Uranus; both cases are 6-body problems. The methods of integration used, the error accumulation rates encountered, and the results achieved are presented. Thus-far-unknown long periodic variations in the major semiaxes of the outer planets with periods of the order of 1 million years are discovered through these investigations.
