Proposal Title: RADAR IMAGING OF KLEOPATRA
ABSTRACT:
Kleopatra, the leading candidate for a metallic object in the main belt, is thought to have a complex, extremely
elongated, possibly bifurcated shape with maximum dimension of more than 230 km. This November's opposition
oers the most favorable opportunity for radar investigation of Kleopatra until 2013. We propose intensive
delay-Doppler imaging with the objective of obtaining a detailed physical model (including denition of most of
the shape at the several-kilometer level as well as accurate estimation of the surface's bulk density and metal
abundance. The geometric circumstances for this experiment are excellent, and the observing and
shape-reconstruction techniques are well established.
