<p>Originally published here: <a href="https://www.thingiverse.com/thing:3320748">1 Ceres scaled one in ten million by tato_713 - Thingiverse</a></p><p>This model is made by myself using MATLAB R2016a using the IQC model made by Park, R.S. and Buccino, from the data of the Dawn mission. It's scaled to 1 in 107 or one in ten million. The model of it has nearly 10cm in diameter. 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. 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>1 Ceres</h4><p>Ceres is the largest object in the <a href="/tato_713/collections/main-belt-asteroids">Main Asteroid Belt</a>. It was one of the originally dwarf planet recognised in the 2006 planet redefinition. It was the first minor planet discovered, and it was first categorised as a planet. One of the most notable surface feature is the Occator crater, responsable of the "bright spot" on Ceres.</p><ul><li><strong>Type:</strong> Dwarf planet.
