TL;DR: In this article, the dynamics of low-altitude, near-polar orbits around planetary satellites, taking into account the gravitational attraction of a third body and the non-uniform distribution of mass of the planetary satellite, is studied.
Journal Article
A study of the impact of the initial energy in a close approach of a cloud of particles
TL;DR: In this article, the effects of a close approach in the three-dimensional space between a planet and a cloud of particles, with the goal of understanding the dispersion of this cloud in terms of the variations of velocity, energy, angular momentum and inclination, were studied.
Swing-By Maneuvers for a Cloud of Particles with Planets of the Solar System
TL;DR: In this article, the authors studied the swing-by maneuver between one of the planets of the Solar System and a cloud of particles, where the motion is assumed to be planar for all the particles and the dynamics given by the "patched-conic" approximation is used.
Journal ArticleDOI
On the effects of each term of the geopotential perturbation along the time I: Quasi-circular orbits
TL;DR: In this paper, a time integration of the perturbing acceleration coming from each harmonic of the geopotential during a time interval T is presented, which represents the total velocity contribution of a specific harmonic during the period T. The perturbations of the Sun, the Moon, and the direct solar radiation pressure with eclipses are considered.
Journal ArticleDOI
Classification of Out-of-Plane Swing-By Trajectories
TL;DR: In this article, the authors studied the swing-by maneuvers under the model given by the three-dimensional restricted three-body problem, and the results generated here have a potential use to solve optimal problems, such as nding trajectories that satisfy some given constraints with some parameters being extremized (position, velocity, etc.).
