Combined analyses of gravity and topography can yield useful information about the interior structures of planetary bodies [1–4]. Based on radio tracking of the Cassini spacecraft, we present an estimate of the gravity field of Saturn's large moon Rhea. Combining this with a shape model based on limb profile analyses, we attempt to constrain Rhea's internal structure, concluding that the core likely exhibits some excess flattening.

Abstract

Combined analyses of gravity and topography can yield useful information about the interior structures of planetary bodies [1–4]. Based on radio tracking of the Cassini spacecraft, we present an estimate of the gravity field of Saturn's large moon Rhea. Combining this with a shape model based on limb profile analyses, we attempt to constrain Rhea's internal structure, concluding that the core likely exhibits some excess flattening.
