Masses are unavailable for the Trojans of Tethys (Calypso and Telesto) and Dione Helene and Polydeuces, as well as the tiny satellite-region moons Methone, Anthe, Pallene, and Polydeuces, because none of these is massive enough to measurably perturb any nearby or resonant moons

It is reasonable to question the assumption that the moonlets are point masses in calculating the Roche lobe dimensions (shape and critical density) because they are clearly extended bodies. However, no self-gravitating extended body with a homogeneous interior and the low densities found for the moons in this study is even stable in the ring region, and bodies with dense cores and under-dense mantles differ in their dimensions from those of a point-mass Roche lobe by at most ∼5
