<p>Originally published here: <a href="https://www.thingiverse.com/thing:3320495">4 Vesta scaled one in ten million by tato_713 - Thingiverse</a></p><p>This model is made by myself using MATLAB R2016a on the height map of the USGS site from the Dawn mission. On this scale the <a href="https://www.thingiverse.com/thing:3419235">Moon</a> is a basketball and <a href="https://www.thingiverse.com/thing:3513228">Mars</a>' moons <a href="https://www.thingiverse.com/thing:3863992">Phobos and Deimos</a> are 2 and 1 mm respectively. It's also included a one in four million scaled model for more details. In this scale the model is 14cm in diameter.</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>4 Vesta</h4><p>Vesta is the second largest object in the main asteroid belt, the largest asteroid considering <a href="https://www.thingiverse.com/thing:3320748">Ceres</a> as a dwarf planet but not an asteroid. It is one of the biggest object not hidrostaticaly relaxed, so it's automatically excluded from being a dwarf planet. Its irregular shape is carved by many features like the south pole Rheasilvia crater, and the multiple large equatorial fosae. Vesta is though to be a protoplanet, a remnant of a failed planet. It has a differentiated nucleus, which means that is was a planet primordial block, but its acreation was interrupted before the formation of a larger body.</p><ul><li><strong>Type:</strong> Asteroid.
