| Abstract: | The shapes and gravitational moments of tidally and rotationally distorted satellites with nonuniform internal density distributions are calculated. Spacecraft determinations of the radii and (a) the gravitational moments of some satellites of Jupiter and Saturn, particularly Io, Ganymede and Titan or (b) the shapes of some others, particularly Mimas and Tethys, could provide unambiguo3s evidence of either internal differentiation or orbital evolution. The shapes of rotationally distorted asteroids are discussed briefly. |
