Asteroid Shape Models

Asteroid models

Scientist: Michael Busch

Radar pulses sent from Earth reflected off these asteroids, and sophisticated software derived their approximate shapes!  There are a few dozen asteroid files linked from this page, and they're all in the .OBJ file format, which is easily convertible to other file formats, and is natively understood by many as well (including Unity).  Note that the models are to-scale, and some of them are gigantic relative to others!  The narrowbeam radar pulses that mapped these asteroids are among the clearest and most receivable signals that humanity is sending into space!
