Abstract Photometric data on 17 binary near-Earth asteroids (15 of them are certain detections, two are probables) were analysed and characteristic properties of the near-Earth asteroid (NEA) binary population were inferred. We have found that binary systems with a secondary-to-primary mean diameter ratio D s / D p ⩾ 0.18 concentrate among NEAs smaller than 2 km in diameter; the abundance of such binaries decreases significantly among larger NEAs. Secondaries show an upper size limit of D s = 0… Expand
Photometric Survey for Asynchronous Binary Asteroids
Asynchronous binary asteroids have been found to be abundant among fast-spinning near-Earth asteroids (NEAs) smaller than 2 km in diameter; Pravec et al. (2005, Icarus, submitted) derived that 15 +/4Expand
Orbital evolution of small binary asteroids
Abstract About 15% of both near-Earth and main-belt asteroids with diameters below 10 km are now known to be binary. These small asteroid binaries are relatively uniform and typically contain aExpand
Small binary asteroids and prospects for their observations with Gaia
Abstract We studied a capability of Gaia to detect binary systems among small asteroids (with diameters ≲ 10 km ) by observing their photocenter oscillation. The closest binary systems with orbitalExpand
Binary asteroid population. 2. Anisotropic distribution of orbit poles of small, inner main-belt binaries
Abstract Our photometric observations of 18 main-belt binary systems in more than one apparition revealed a strikingly high number of 15 having positively re-observed mutual events in the returnExpand
Binary asteroid population 1. Angular momentum content
Abstract We compiled a list of estimated parameters of binary systems among asteroids from near-Earth to trojan orbits. In this paper, we describe the construction of the list, and we present resultsExpand
Physical Characterization and Origin of Binary Near-Earth Asteroid (175706) 1996 FG3
The near-Earth asteroid (NEA) (175706) 1996 FG3 is a particularly interesting spacecraft target: a binary asteroid with a low-?v heliocentric orbit. The orbit of its satellite has provided valuableExpand
Binary near-Earth asteroid formation: Rubble pile model of tidal disruptions
We present numerical simulations of near-Earth asteroid (NEA) tidal disruption resulting in bound, mutually orbiting systems. Using a rubble pile model we have constrained the relative likelihoodsExpand
Potentially hazardous asteroid (185851) 2000 DP107 was the first binary near-Earth asteroid to be imaged. Radar observations in 2000 provided images at 75 m resolution that revealed the shape, orbit,Expand
Binary Minor Planets
A review of observations and theories regarding binary asteroids and binary transNeptunian objects [collectively, binary minor planets (BMPs)] is presented. To date, these objects have beenExpand
Main belt binary asteroidal systems with circular mutual orbits
In 2003, we initiated a long-term adaptive optics campaign to study the orbit of various main-belt asteroidal systems. Here we present a consistent solution for the mutual orbits of four binaryExpand


Compositional Investigation of Binary Near-Earth Asteroid 66063 (1998 RO1): A Potentially Undifferentiated Assemblage
It is now thought that approximately 16% of all asteroids among the near-Earth population may be binary objects. Several independent lines of evidence, such as the presence of doublet craters on theExpand
Binary Asteroids in the Near-Earth Object Population
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. Expand

Keck observations of near-Earth asteroids in the thermal infrared

Two Periods of 1999 HF1—Another Binary NEA Candidate
Photometric observations of 1999 HF1 reveal that its lightcurve has two components of low amplitudes (0.10–0.12 mag) and different periods (2.3191 and 14.02 h). It is likely another binary near-EarthExpand
Occultation/Eclipse Events in Binary Asteroid 1991 VH
Abstract We present the results of photometric observations of the Apollo asteroid 1991 VH. Its lightcurve consists of two components: the first is the rotational lightcurve with period P s =Expand
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), formedExpand
