So _1_6_10_7 is 1:600000000 or one in 60 million.&nbsp;</p><h4>21 Lutetia</h4><p>Lutetia is a medium sized asteroid of the <a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49291">Main Asteroid Belt</a>. It is one of the many asteroid considered a "protoplanet" or planetesimal, because it is though to be one of the block of a forming planet that never get together because of constant impacts and interactions with <a href="https://www.thingiverse.com/thing:3928031">Jupiter</a>'s gravity. Its spectral type is M (metallic, iron) but with trace of non-metallic compounds, like carbon and silicate.</p><ul><li><strong>Type:</strong> Asteroid.</li><li><strong>Orbit:</strong> Sun.
