Orbital Capture of Ejecta into Periodic Orbits around Binary Asteroid (65803) Didymos

open access: yesThe Planetary Science Journal
The successful impact of the Double Asteroid Redirection Test (DART) spacecraft on Dimorphos enabled the first-ever extensive observation of a postimpact ejecta tail from a binary asteroid system.

An Earth Encounter as the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH

open access: yesThe Planetary Science Journal
Among binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown. In this work, we demonstrate that a past close encounter with Earth could

Earth's Minimoons: Opportunities for Science and Technology

open access: yesFrontiers in Astronomy and Space Sciences, 2018
Twelve years ago the Catalina Sky Survey discovered Earth's first known natural geocentric object other than the Moon, a few-meter diameter asteroid designated 2006 RH120. Despite significant improvements in ground-based telescope and detector technology

Disintegration and Skipping Dynamics of Bilobate‐Shaped Meteoroids for Generating Ultra‐Long Strewn Fields

open access: yesEarth and Space Science
The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution. The

Near-Earth Asteroid Satellite Spins Under Spin-Orbit Coupling

open access: yes, 2015
We develop a fourth-order numerical integrator to simulate the coupled spin and orbital motions of two rigid bodies having arbitrary mass distributions under the influence of their mutual gravitational potential. We simulate the dynamics of components in
