Abstract

The shape model of Ostro et al.(2000) for (216) Kleopatra-obtained from inversion of the radar data (Hudson & Ostro 1994)-is compared to the high resolution interferometric observations of the HST/FGS astrometer, and additionally to observed lightcurves and stellar occultations data. It appears that the radar nominal-model, while being in global agreement with these data, doesn t adequately reproduce all of them. In particular the flattening seems to be underestimated by~ 20%. The HST/FGS observations should provide valuable ...
