VIRTIS thermal mapping suggested a low-porosity surface and the absence of a thick regolith layer (Leyrat et al. 2011). e. a submillimeter and millimeter radiometer and spectrometer (Gulkis et al. 2007), were consistent with this interpretation, supporting a high thermal inertial surface, characteristics of rock-dominated regolith rather than the powdered-regolith surface of the Moon (Gulkis et al.

For example, spacecraft data 22 I. Bertini proved that asteroids possess a magnetic field, telling us that ferromagnetic materials were indeed present in the forming solar nebula. Asteroids have satellites, as also proved later to a larger extent with the use of radar data. This means the collisional environment of these objects was still active in recent times. Collisions have shaped the surface of all asteroids visited so far and low-velocity accretion of smaller bodies, leading to the formation of larger rubble-pile structures, has been proved to exist.

Because of Mathilde’s slow rotation, only about 60% of its surface was seen during the flyby (Veverka et al. 1997b). Its irregular shape was modeled with a triaxial ellipsoid having dimensions of 66×48×44 km3 (Veverka et al. 1999). A picture of Mathilde taken by NEAR is shown in Fig. 3. 4 km, comparable to the mean radius of the body. No evidences of ejecta were found on the surface. It was immediately considered quite exceptional that Mathilde survived many major catastrophic events without being completely destroyed.
