Methone, Anthe and Pallene scaled one in eighty thousand

These tiny moons of Saturn, that orbit between Mimas and Enceladus, are represented here as ellipsoids because they are literally ellipsoidal without any noticeable feature in their surfaces. This soft (or flat) relief is because the satellites are recently formated, probably from material ejected from one of the bigger moons, or accreted from an old ring. Methone and Anthe have coorbital arc rings; while Pallene has a complete ring along its orbit.
The file's names explained: name_1_x_10_y.stl is 1 : x * 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million.
