Radar Investigations of Asteroids [PDF]
Radar investigations of asteroids, including observations during 1984 to 1985 of at least 8 potential targets and continued analyses of radar data obtained during 1980 to 1984 for 30 other asteroids is proposed.

Minor satellites and the Gaspra encounter [PDF]
Observational evidence, especially from occultations and radar, indicate that satellites of minor planets are numerous and commonplace. This leads to the prediction that the Galileo spacecraft will find many such 'minor satellites' at the upcoming close ...

Numerical Determination of the Gravitational Cross Sections of an Accreting Binary
The Astrophysical JournalA significant amount of work has been devoted to the study of small binary solar system objects. The majority of these binaries, especially among the near-Earth or main belt asteroids, have small radius ratios, implying a large difference in size between

Spin–Orbit Coupling of the Ellipsoidal Secondary in a Binary Asteroid System
The Astronomical JournalIn our solar system, spin–orbit coupling is a common phenomenon in binary asteroid systems, where the mutual orbits are no longer invariant due to exchange of angular momentum between translation and rotation.

Beyond Point Masses. II. Non-Keplerian Shape Effects Are Detectable in Several TNO Binaries
The Astronomical JournalAbout 40 trans-Neptunian binaries (TNBs) have fully determined orbits with about 10 others being solved except for breaking the mirror ambiguity. Despite decades of study, almost all TNBs have only ever been analyzed with a model that assumes perfect ...

Detection of Close Kuiper Belt Binaries with HST WFC3
The Planetary Science JournalBinaries in the Kuiper Belt are common. Here we present our analysis of the Solar System Origins Legacy Survey (SSOLS) to show that using a point-spread function (PSF)-fitting method can roughly double the number of binaries identified in that data set ...
