Journal ArticleDOI
Binary asteroids in the near-Earth object population.
Jean-Luc Margot,Michael C. Nolan,Lance A. M. Benner,Steven J. Ostro,Raymond F. Jurgens,Jon D. Giorgini,M. A. Slade,Donald B. Campbell +7 more
TL;DR: This system and other binary near-Earth asteroids have spheroidal primaries spinning near the breakup point for strengthless bodies, suggesting that the binaries formed by spin-up and fission, probably as a result of tidal disruption during close planetary encounters, may be binary systems.
Journal ArticleDOI
Radar Imaging of Binary Near-Earth Asteroid (66391) 1999 KW4
Steven J. Ostro,Jean-Luc Margot,Lance A. M. Benner,Jon D. Giorgini,Daniel J. Scheeres,Eugene G. Fahnestock,Stephen B. Broschart,Julie Bellerose,Michael C. Nolan,Christopher Magri,Petr Pravec,P. Scheirich,Randy Rose,Raymond F. Jurgens,Eric De Jong,S. Suzuki +15 more
TL;DR: High-resolution radar images reveal near-Earth asteroid (66391) 1999 KW4 to be a binary system that is dominated by an equatorial ridge at the object's potential-energy minimum and has exotic physical and dynamical properties.
Journal ArticleDOI
Shape model and surface properties of the OSIRIS-REx target Asteroid (101955) Bennu from radar and lightcurve observations
Michael C. Nolan,Christopher Magri,Ellen S. Howell,Lance A. M. Benner,Jon D. Giorgini,Carl Hergenrother,R. Scott Hudson,Dante S. Lauretta,Jean-Luc Margot,Steven J. Ostro,Daniel J. Scheeres +10 more
TL;DR: In this paper, the shape of the near-Earth Asteroid (101955) Bennu was determined based on radar images and optical lightcurve data, along with an initial determination of the rotation period derived from them, simplified and improved the shape modeling.
Journal ArticleDOI

TL;DR: The terminal navigation of the Near Earth Asteroid Rendezvous (NEAR) spacecraft during its close flyby of asteroid 253 Mathilde involved coordinated efforts to determine the heliocentric orbits of the spacecraft and Mathilde and then to determine its relative trajectory with respect to Mathilde.
Journal ArticleDOI
Radio science results during the NEAR-shoemaker spacecraft rendezvous with eros
Donald K. Yeomans,Peter G. Antreasian,Jean-Pierre Barriot,Steve Chesley,David W. Dunham,Robert W. Farquhar,Jon D. Giorgini,C. E. Helfrich,Alex S. Konopliv,James V. McAdams,J. K. Miller,William M. Owen,Daniel J. Scheeres,Peter C. Thomas,Joseph Veverka,B. G. Williams +15 more
TL;DR: The mass of asteroid 433 Eros, its lower order gravitational harmonics, and rotation state are determined, using ground-based Doppler and range tracking of the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker spacecraft and images of the asteroid's surface landmarks.
