Abstract
Abstract The Near Earth Asteroid Rendezvous (NEAR) performed a flyby of the C-type main belt asteroid 253 Mathilde and an orbital study of the S-type near-Earth asteroid 433 Eros. These asteroid datasets provide a basis for inferences regarding physical properties and internal structure. The NEAR flyby of Mathilde revealed a heavily cratered surface with at least five giant craters (close to geometric saturation). Mathilde's density was unexpectedly low at 1.3 ± 0.3 g cm −3 , indicating a high porosity. Such a high porosity may be consistent with a rubble pile structure and may favor a compressional style of cratering. There are structural features, such as a 20...
