Main belt binary asteroidal systems with circular mutual orbits
Physical Properties of (2) Pallas
The small binary asteroid ( 939 )
In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic qua ntity. We aim here to characterize the surface composition, mutual orbit , size,


Mass and density of Asteroid 121 Hermione from an analysis of its companion orbit
Near-IR imaging of Asteroid 4 Vesta
Studying binary asteroids with NGS and LGS AO systems
Since the discovery of Dactyl orbiting around Ida by the Galileo spacecraft in 1993, over twenty-five binary asteroid systems have been discovered using radar, direct imaging and Adaptive Optics
Discovery of a moon orbiting the asteroid 45 Eugenia
Evidence for asteroidal satellites (moons) has been sought for decades, because the relative frequency of such satellites will bear on the collisional history of the asteroid belt and the Solar
Adaptive optics observations of asteroid 216 Kleopatra
The large main-belt asteroid (216) Kleopatra has been for long suspected to be a binary object, mainly due to its large lightcurve amplitude. However, recent observations suggest that it is a single
Triaxial equilibrium ellipsoids among the asteroids
Discovery of the triple asteroidal system 87 Sylvia
The unambiguous detection of a triple asteroidal system in the main belt, composed of a 280-km primary (87 Sylvia) and two small moonlets orbiting at 710 and 1,360 km, which was most probably formed through the disruptive collision of a parent asteroid.
Binary Asteroids and the Formation of Doublet Craters
Abstract At least 10% (3 out of 28) of the largest known impact craters on Earth and a similar fraction of all impact structures on Venus are doublets (i.e., have a companion crater nearby), formed
A three-dimensional solution for the orbit of the asteroidal satellite of 22 Kalliope
Extreme Kuiper Belt Object 2001 QG298 and the Fraction of Contact Binaries
Extensive time-resolved observations of Kuiper belt object 2001 QG298 show a light curve with a peak-to-peak variation of 1.14 ± 0.04 mag and single-peaked period of 6.8872 ± 0.0002 hr. The mean
