Abstract
Measurements from the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker Laser Rangefinder (NLR) indicate that asteroid 433 Eros is a consolidated body w ith a complex shape dominated by collisions. The offset between the asreroi d's center of mass and center of figure indicates a small deviation from a homogeneous internal structure that is most simply explained by variations in mechanical structure. Regional-scale relief and slope distributions show evidence for control of topography by a competent substrate. impact crater morphology is influenced by both gravity and structural control. Small-sca le topography reveals ridges and grooves that may be generated by impact-re lated fracturing.
