Like most of my topographical models its relief was exaggerated to make it more visible in the printed model.</p><p>The file's names explained:<i>name_1_x_10_y.stl</i> is 1 : x* 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million.&nbsp;</p><h4>Mars</h4><p>Mars is the only planet in the Solar System aside from the <a href="https://www.prusaprinters.org/print/57301/edit">Earth</a> that could ever hold liquid water. It once has oceans and a Earth like atmosphere, but without a magnetosphere, the solar winds eroded the atmosphere at the point that it cannot sustain pressure nor temperature for liquid water. At now, Mars' atmosphere pressure is less than 1% of that of Earth at the surface. It is speculated that at these early conditions there could be primitive life forms. Most of the water was dissociated or condensed remaining as ice below the surface or in the poles ice cap. The planet surface has several noticeable features: the Olympus Mons, the biggest volcano on the Solar System; and the Valles Marineris. The entire northern hemisphere has a low elevation, that could be a giant impact basin, probably caused by an impact of an object of the size of <a href="https://www.prusaprinters.org/prints/57250-pluto-and-charon-with-known-topography-scaled-one-">Pluto</a>. Mars has two asteroid like moons, <a href="https://www.thingiverse.com/thing:3863992">Phobos and Deimos</a>. They are too small to make in the same scale (less than 0.3mm).</p><ul><li><strong>Type:</strong> Planet.&nbsp;</li><li><strong>Orbit:</strong> Sun.&nbsp;</li><li><strong>Orbital period:</strong> 686.971 d.&nbsp;</li><li><strong>Composition:</strong> Silicate rock.
