This model was rendered using MATLAB R2016a on the ICQ model of the PSI made by Robert Gaskell from the data of the Cassini mission. It's scaled to 1 in 4 x 106 or one in four million and 1 in 2 x 106 or one in two million.
The file's names explained: name_1_x_10_y.stl is 1 : x * 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.
Phoebe is the biggest irregular satellite of Saturn. The irregular satellites are moons with a high inclination from its planet plane, high orbit excentricity and retrograde orbit. It is thought that irregular satellites are the result of the capture of the object by the parent planet. Phoebe has a different interior, which means that at some point in its history it was almost rounded, but then it was deformed by repeated impacts.
Orbit: Saturn. Irregular (hightly inclined and retrograde).
Orbital period: 550.564 d.
Composition: Icy body, differenciated interior, rocky core.
Density: 1.638 g/cm3.
Dimensions: 218.8 km × 217.0 km × 203.6 km.
Model scale: 1:4x106 (5cm) 1:2x106 10cm)
