<p>Originally published here: <a href="https://www.thingiverse.com/thing:3436882">Amalthea scaled one in four million by tato_713 - Thingiverse</a></p><p>This model was rendered using MATLAB R2016a on the ICQ model of the PSI made by Philip Stooke from the data of the Galileo and Voyager missions. The original model has a very low resolution, so the model was very "poly" look. To avoid this I interpolate into much more points than the original. It's scaled to 1 in 4 x 10^6 or one in four million and 1 in 2 x 106 or one in two million.&nbsp;</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>J5 Amalthea</h4><p>Amalthea is the biggest moon of <a href="https://www.thingiverse.com/thing:3928031">Jupiter</a> that it's not one of the Galilean Moon (<a href="https://www.thingiverse.com/thing:3419212">Io</a>, <a href="https://www.thingiverse.com/thing:3419443">Europa</a>, <a href="https://www.thingiverse.com/thing:3686218">Ganymede</a> and <a href="https://www.thingiverse.com/thing:3686246">Callisto</a>). Its shape is very irregular, because it is a rubble pile. In astronomy, rubble piles are objects formed by the accretion of many smaller objects, but without the melting required for making the object spherical.</p><ul><li><strong>Type:</strong> Satellite.&nbsp;</li><li><strong>Orbit:</strong> Jupiter&nbsp;</li><li><strong>Orbital period:</strong> 11 h 57 min 23 s.&nbsp;</li><li><strong>Composition:</strong> Icy body, rubble pile.&nbsp;</li><li><strong>Density:</strong> 0.857 g/cm3.</li><li><strong>Dimensions:</strong> 250 km × 146 km × 128 km.&nbsp;</li><li><strong>Model scale:</strong> 1:4x106 (6cm) 1:2x106 (12cm)</li></ul><h4>References</h4><ul><li><a href="https://sbn.psi.edu/pds/resource/stkshape.html">"Stooke.
