Description:
Measurements from the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker Laser Rangefinder (NLR) indicate that asteroid 433 Eros is a consolidated body with a complex shape dominated by collisions. The offset between the asteroid'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-scale topography reveals ridges and grooves that may be generated by impact-related fracturing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zuber -- Smith -- Cheng -- Garvin -- Aharonson -- Cole -- Dunn -- Guo -- Lemoine -- Neumann -- Rowlands -- Torrence -- New York, N.Y. -- Science. 2000 Sep 22;289(5487):2097-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.
