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

TL;DR: In this article, photometric data on 17 binary near-Earth asteroids (15 of them are certain detections, two are probables) were analyzed and characteristic properties of the near Earth asteroid (NEA) binary population were inferred.
Journal ArticleDOI

Steven R. Chesley,Davide Farnocchia,Michael C. Nolan,David Vokrouhlický,Paul W. Chodas,Andrea Milani,Federica Spoto,Benjamin Rozitis,Lance A. M. Benner,William F. Bottke,Michael W. Busch,Joshua P. Emery,Ellen S. Howell,Dante S. Lauretta,Jean-Luc Margot,Patrick A. Taylor +15 more
TL;DR: The OSIRIS-REx asteroid sample return mission target, (101955) Bennu (formerly 1999 RQ 36), is a half-kilometer near-Earth asteroid with an extraordinarily well constrained orbit as mentioned in this paper.
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.
