I've made a website to track Elon Musk's Roadster that was launched on top of the Falcon Heavy rocket lately. Check it out here.

Models are given in Stanford Triangle Format (PLY) and Alias Waveform Format (OBJ) - you can use MeshLab or any other tool to convert them to other formats.

Please note that the models are in planetocentric coordinate system, with Z axis passing through north pole. Actual rotational axis may differ from planetocentric poles, especially for small irregular bodies.

This object does not have textures yet and is being displayed as a solid gray shape.
