Space Debris [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractMan-made, artificial space debris is of interest to the study of interplanetary dust for two reasons: (1) In many regions of Earth orbital space, the space debris flux is larger than the natural meteoroid flux, complicating the study of interplanetary dust, and (2) models and experiments developed to understand space debris may have application

Proper elements for space debris

open access: yesCelestial Mechanics and Dynamical Astronomy, 2022
Abstract Proper elements are quasi-invariants of a Hamiltonian system, obtained through a normalization procedure. Proper elements have been successfully used to identify families of asteroids, sharing the same dynamical properties.
