Shape and Appearance

Kleopatra is unique among asteroids due to its distinctive shape. Unlike the round or oblong shape of most asteroids, Kleopatra has a complex shape with three distinct lobes, resembling a dog bone. The asteroid's shape was discovered using radar observations made by the Arecibo Observatory, Puerto Rico.

Spin and Rotational Motion

Kleopatra has one of the most bizarre spins in the solar system. It rotates around one of its long axes every five hours, while tumbling end over end every 17.4 hours. That is to say, it spins like a top while also circling around two different axes, like a wobbling plate. The cause of this unusual rotation is still unclear, but it is thought to be related to the asteroid's shape and composition.
