So _1_6_10_7 is 1:600000000 or one in 60 million.&nbsp;</p><h4>433 Eros</h4><p>Eros, compared with <a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49291">Main Belt asteroids</a> is relatively small, with 34km long, but it's one of the two biggest <a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49820">Near Earth asteroids</a> (NEA), along with Ganymed (not <a href="https://www.thingiverse.com/thing:3686218">Ganymede</a>, one of the <a href="https://www.thingiverse.com/thing:3928031">Jupiter</a>'s moon). At present, Eros is part of the Amor group, which means that it cross the orbit of <a href="https://www.thingiverse.com/thing:3513228">Mars</a>, but the NEAs' orbits are unstable. In a few million of years Eros could change its orbit to a lower <a href="https://www.prusaprinters.org/prints/57301-earth-with-exaggerated-topography-scaled-one-in-si">Earth</a> crossing one, becoming a member of the Apollo or Aten group. Depending on how close it became to the Earth, it could be a Potentially Hazardous object (PHO), an object capable of intersect and impact on Earth. If it does, it would cause a greater damage than the Chicxulub impactor, the asteroid or comet that triggered the K-T event (in which the non-avian dinosaurs became extincts), since it is 3 to 5 times bigger.</p><ul><li><strong>Type:</strong> Near Earth asteroid.&nbsp;</li><li><strong>Orbit:</strong> Sun.
