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

The Dynamics of NEO Binary Asteroids [PDF]
AbstractThe dynamics of binary Near-Earth objects (NEO) are discussed and a simple model for the study of their dynamics is introduced. Main results on the motion and stability of binary asteroids are reviewed. The effect of perturbations external to the binary system, including solar gravity, solar radiation pressure, and planetary gravity, are ...

Radiation Forces and Trajectory of Hayabusa2♯ Target 1998 KY26
Small near-Earth asteroid 1998 KY _26 has recently become an object of interest because it is the target of the Hayabusa2 ♯ mission and because challenges in fitting its astrometric data have led to classifying it as a dark comet.

Effects of asteroid belt and oblateness on the stability and orbits near triangular Lagrange points
This study investigates the dynamics of an infinitesimal body within the context of the restricted three-body problem, incorporating perturbations arising from the asteroid belt and the oblateness effects of the three bodies.

Fully Coherent Model of Dynamics around Binary Asteroids: Application to Didymos and the DART Impact
The dynamical environment around binary asteroids has been studied in depth, but these models typically make assumptions about the eccentricity, shapes, or rotational stability of the asteroids.
