These models were rendered using MATLAB R2016a on the ICQ models of the PSI made from the data of the Cassini mission.
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.
S12 Helene
Similar to Telesto with Tethys, Helene orbits Saturn 60 degrees preceding Dione, in the Lagrangian point L4. Is the biggest known trojan moon. There is a smaller moon (about 3 km length) named Polydeuces orbiting the L5 point of the Saturn-Dione reference system. This kind of moons are though to be formed from the ejected material from impacts on the moon.
