Abstract
Radar observations of the main-belt, M-class asteroid 216 Kleopatra reveal a dumbbell-shaped object with overall dimensions of 217 kilometers by 94 ki lometers by 81 kilometers (+/-25%). The asteroid's surface properties are c onsistent with a regolith having a metallic composition and a porosity comp arable to that of Lunar soil. Kleopatra's shape is probably the outcome of an exotic sequence of collisional events, and much of its interior may have an unconsolidated rubble-pile structure.
