Lunar ejecta origin of near-Earth asteroid Kamo'oalewa is compatible with rare orbital pathways. [PDF]

Commun Earth Environ, 2023
Near-Earth asteroid, Kamo’oalewa (469219), is one of a small number of known quasi-satellites of Earth; it transitions between quasi-satellite and horseshoe orbital states on centennial timescales, maintaining this dynamics over megayears. The similarity

Spin–Orbit Coupling of the Ellipsoidal Secondary in a Binary Asteroid System

The Astronomical Journal
In 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.

Asteroid Impact Satellite Optimization

This paper proposes an optimization algorithm inspired by the physical phenomenon of asteroid impacts on satellites, called the Asteroid Impact Satellite Optimization (AISO). This algorithm simulates the dynamics of asteroid impacts on satellites and incorporates three innovative mechanisms: multi-impact coordination, fragment self-organization, and ...

Beyond Point Masses. II. Non-Keplerian Shape Effects Are Detectable in Several TNO Binaries

The Astronomical Journal
About 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 Journal
Binaries 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 ...
