The orbits of the major satellites of Saturn.

Abstract

Strugnell & Taylor's (1990) catalogue of observations of the major satellites of Saturn was augmented by several thousand additional observations. Theories of the motions of the satellites (excluding Hyperion) were fitted to these observations using a weighted least-squares procedure in order to derive improved values of the orbital elements and other parameters of the system, including the masses of the four inner satellites and the dynamical form factors J 2 and J 4 of Saturn.
