<p>Originally published here: <a href="https://www.thingiverse.com/thing:3419489">Hyperion 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 from the data of the Cassini mission.</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.</p><h4>S7 Hyperion</h4><p>Hyperion is one of the biggest not rounded moons of <a href="https://www.thingiverse.com/thing:3930295">Saturn</a>. It's larger than <a href="https://www.prusaprinters.org/prints/57261-phoebe-scaled-one-in-four-million">Phoebe</a>, but lighter. This is because of its high porosity, more than a half of its volume is vacuum. The proximity with <a href="https://www.thingiverse.com/thing:3501867">Titan</a> makes its rotation chaotic, which means that the poles and hemispheres cannot be defined. Because of this the labels "north" and "south" in the model's file names and the model inclination are arbitrary.</p><ul><li><strong>Type:</strong> Satellite&nbsp;</li><li><strong>Orbit:</strong> Saturn.&nbsp;</li><li><strong>Orbital period:</strong> 21.276 d.&nbsp;</li><li><strong>Rotational period:</strong> 13 d.
