This model was rendered using MATLAB R2016a on the ICQ model of the NASA PDS site made from the data of the Rosetta mission.
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.
21 Lutetia
Lutetia is a medium sized asteroid of the Main Asteroid Belt. 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 Jupiter's gravity. Its spectral type is M (metallic, iron) but with trace of non-metallic compounds, like carbon and silicate.
