Asteroid 216 Kleopatra

The main-belt asteroid shaped like a dog bone, with two moons of its own.

The actual model file, as it will be printed. Drag to turn it.

Kleopatra is roughly 270 kilometres end to end and genuinely bone-shaped: two lobes joined by a neck, most likely the result of a collision that failed to break it apart. Radar gave us the shape long before any camera got close.
