Shape Natural satellite

the relative masses of natural satellites of solar system. mimas, enceladus, , miranda small visible @ scale. irregularly shaped natural satellites, added together, small visible.

neptune s moon proteus largest irregularly shaped natural satellite. other known natural satellites @ least size of uranus s miranda have lapsed rounded ellipsoids under hydrostatic equilibrium, i.e. round/rounded satellites . larger natural satellites, being tidally locked, tend toward ovoid (egg-like) shapes: squat @ poles , longer equatorial axes in direction of primaries (their planets) in direction of motion. saturn s moon mimas, example, has major axis 9% greater polar axis , 5% greater other equatorial axis. methone, of saturn s moons, around 3 km in diameter , visibly egg-shaped. effect smaller on largest natural satellites, own gravity greater relative effects of tidal distortion, orbit less massive planets or, in case of moon, @ greater distances.
