Radar images organized by relative rotation phase.
 Time delay (range) increases toward the bottom and 
Doppler frequency increases toward the right, so the asteroid's 
rotation is counterclockwise. 

Shape reconstruction results.
 Each quadrant shows Arecibo radar images from one
  date (top), corresponding images calculated from the shape model
  (middle), and corresponding plane-of-sky views of the model
  (bottom).  Each scale bar is 100 km long. 

Views of the Kleopatra shape model parallel to its principal axes of inertia.
 The scale bar is 100 km long. 

Gravitational slopes on Kleopatra.
 Their shallowness suggests a surface covered by
  unconsolidated porous debris.  [Graphics: Shigeru Suzuki and Eric
