These models were rendered using MATLAB R2016a the data of the Stardust mission from the PDS site.
The file's names explained: name_1_x_10_y.stl is 1 : x* 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million.
Wild 2 is a quite active, nearly ellipsoidal, short period comet. These comets are originally from the Kuiper Belt, and were disrupted by Jupiter's gravity into a 6 year period orbit in September of 1974. It has big craters in its surface, most likely made by the material expelled from the comet rather than impact events.
The author marked this model as their own original creation. Imported from Thingiverse.
