5535 Annefrank approximate shape scaled one in eighty thousand

This is not a true shape model of the asteroid, but an approximation based on the albedo map of the side of the asteroid, plotted in an arrow tip like ellipsoid, using MATLAB R2016a.

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. 

5535 Annefrank

This small asteroid is part of the Flora family, like Gaspra, the rubble resulted from the collision millions years ago of the primordial asteroid Flora with a smaller counterpart. Its arrow tip shape is though to be the result of million of years of the erosion of space weather and microasteroid collisions.
