Originally published here: Rhea with known topography scaled one in ten million by tato_713 - ThingiverseThis model is made by myself using MATLAB R2016a and Paint.net on the topography map from the blog of Dr. Paul Schenk. The original map has the known topography only, the rest of the Saturn's moon surface topography is unknown because of the low resolution of the images. It's scaled to 1 in 10^7 or one in ten million. This result on a 15cm diameter model. On this scale the Moon is a basketball, and Mars' moons Phobos and Deimos are 2 and 1 mm respectively.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. S5 RheaRhea is the second biggest moon of Saturn in size and mass. It is one of the smallest object known that is rounded by hydrostatic equilibrium. Its surface is heavy cratered similar to other objects in the Solar System without an atmosphere, fluid surface, or tectonic activity. It has been proposed that Rhea has itself a ring system composed of 3 rings, similar to Saturn. This is based on the measured magnetic field occlusion by the Cassini probe. However they could not be seen optically, so the existence of them is unlikely.Type: SatelliteOrbit: Saturn.Orbital period: 4.518 d.Composition: Icy body, differentiated interior.Density: 1.236 g/cm3.Dimensions: 1532.4 km × 1525.6 km × 1524.4 kmModel scale: 1:1x107 (15cm) 1:2x107 (7cm)ReferencesSchenk, P.
