Geometric Mechanics and the Dynamics of Asteroid Pairs [PDF]
Annals of the New York Academy of Sciences, 2004 Abstract:The purpose of this paper is to describe the general setting for the application of techniques from geometric mechanics and dynamical systems to the problem of asteroid pairs. The paper also gives some preliminary results on transport calculations and the associated problem of calculating binary asteroid escape rates.

Mathematics, 2023 We have considered here a novel particular model for dynamics of a non-rigid asteroid rotation, assuming the added mass model instead of the concept of Viscoelastic Oblate Rotators to describe the physically reasonable response of a ‘rubble pile ...

On the dynamics OF NON-RIGID asteroid rotation [PDF]
Acta Astronautica, 2019 We have presented in this communication a new solving procedure for the dynamics of non-rigid asteroid rotation, considering the final spin state of rotation for a small celestial body (asteroid). The last condition means the ultimate absence of the applied external torques (including short-term effect from torques during collisions, long-term YORP ...

Symbolic dynamics in a binary asteroid system
Communications in Nonlinear Science and Numerical Simulation, 2020 We highlight the existence of a topological horseshoe arising from a a--priori stable model of the binary asteroid dynamics. The inspection is numerical and uses correctly aligned windows, as described in a recent paper by A. Gierzkiewicz and P. Zgliczyński, combined with a recent analysis of an associated secular problem.

Morphology of ejecta features from the impact on asteroid Dimorphos [PDF]
Nature CommunicationsHypervelocity impacts play a significant role in the evolution of asteroids, causing material to be ejected and partially reaccreted. However, the dynamics and evolution of ejected material in a binary asteroid system have never been observed directly ...

Mirror formation control in the vicinity of an asteroid [PDF]
, 2008 Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

A Numerical Research on a New Type of Asteroid Flexible Probe
IEEE Access, 2021 The asteroid landing detection is of great scientific and economic value. The traditional landing rigid probe is prone to rebound and escape due to the asteroid’s weak gravity and rugged terrain.

Dynamics of the Hungaria asteroids [PDF]
Icarus, 2010 To try to understand the dynamical and collisional evolution of the Hungaria asteroids we have built a large catalog of accurate synthetic proper elements. Using the distribution of the Hungaria, in the spaces of proper elements and of proper frequencies, we can study the dynamical boundaries and the internal structure of the Hungaria region, both ...
