Description

Originally published here: 21 Lutetia scaled one in two million by tato_713 - Thingiverse

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.

  • Type: Asteroid.
  • Orbit: Sun. Main Asteroid Belt.
  • Orbital period: 3.8 yr.
  • Rotational period: 8 h 10 min.
  • Composition: Iron. M type asteroid. Unusual.
  • Density: 3.4 g/cm3.
  • Dimensions: 121 km × 101 km × 75 km.
  • Model scale: 1:5x105 (22cm) 1:1x106 (11cm) 1:2x106 (5cm)
