Asteroids are complex geophysical worlds, made of different types of material (ice, rock, metal), with a complex interior (differentiated, high porosity), and sometimes with companions (triple asteroids, binary asteroids). To mine an asteroid, you'd combine:
- ASTORB, which is a collection of ephemerides for all numbered asteroids, in one large file (documented on the containing page)
- DAMIT 3D models. DAMIT is a database of hundreds of asteroid models, and also some other information about the asteroids. When browsing for asteroids, you're going to want to download the OBJ files, since those are readily importable. The PNG links provide a visual overview. A description of the other sorts of information to be found at the site.
- RADAR 3D models are a small collection of asteroid models, generated by a different technique. The actual model files are in OBJ format and can be found by going through "Browse" and then "data" links on the site.
- VOBAD is a downloadable database of multiple asteroid systems.
