We review recent results of a project for building a large number of comprehensive physical asteroid models from combined photo- and interferometric observations, occultation timings, and other complementary data. Photometric data form the robust and stable basis for modelling, while particularly HST/FGS-interferometry and CW radar data can add...

Binary or multiple asteroids are important bodies that provide insight into the physical properties of asteroids in general. The knowledge of the components orbit in a binary provides the total mass with high accuracy and generally permits a rough bulk-density estimate [1,2]. We have observed 10 selected binary or multiple asteroids (22...
