Description
Originally published here: Oberon with approximate topography scaled one in ten million by tato_713 - Thingiverse
This model is not based on a topographical map, there is not enough good images to make one, this is based on a high contrast polar map from the USGS site, from which the shadows where interpreted as slopes, so the model is something like an integration of the original one in the spherical elevation coordinate. When the Voyager 2 probe reach Uranus, the system where pointing its north pole of rotation to the Sun. Sometimes, because the south pole or the south hemisphere are defined as the one pointing to the south of the Earth reference, and the right hand rule north pole is 98° tilted (8 degrees to the south), the then visible part is considered to be the south one. I prefer to follow the right hand rule for all my post, so the mapped parts will be the north ones.
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.
Oberon is the second largest, after Titania, and the outermost of the big moon of Uranus. It lays outside the magnetic field of the planet, so it's susceptible to the solar winds and the so called space weather. Like all the big moons of Uranus it is composed of equal amount of water and rock, being differentiated into an ice mantle and a rocky core, with a possible liquid water ocean below the surface.
