54509 YORP scaled one in three thousand

I did not contributed on doing the original file from the collection of asteroid radar models of the PDS site, I just simplify and softened it using Blender. The file's names explained: name_1_x_10_y.stl is 1 : x * 10y. So _1_6_10_7 is 1:600000000 or one in 60 million. 54509 YORP Ivan Osipovich Yarkovsky proposed, in 1900, a mechanism in which a small object can speed up by emitting infra-red radiation, from the solar radiation heating. Shortly, an object rotating the same way as its orbit (prograde) it always moving its hotter side to the trailing side, so the more energetic part is generating a radiation pressure in the moving direction, accelerating the object. A variant of this mechanism was called Yarkovsky-O'Keefe-Radzievskii-Paddack effect (YORP). It is said that a small, irregular object, by the emission and reflection of radiation pressure over its irregularities, a small "paddle" effect is done over the whole asteroid, accelerating the spin of it, and changing the rotation axis. This effect was studied on the asteroid presented here, and it was named by the initials. This asteroid is expected to accelerate up to 3 RPM (20 second period) in the near future, when the centripetal forces will not be enough to hold the asteroid up, and it will break apart into smaller pieces.
