Dynamics in the vicinity of (101955) Bennu: Solar radiation pressure effects in equatorial orbits
Here, we study the dynamical effects of the solar radiation pressure (SRP) on a spacecraftthat will survey the near-Earth rotating asteroid (101955) Bennu when the projected shadowis accounted for. The spacecraft's motion ...
Collecting solar power by formation flying systems around a geostationary point
Terrestrial solar power is severely limited by the diurnal day–night cycle. To overcome these limitations, a Solar Power Satellite (SPS) system, consisting of a space mirror and a microwave energy generator-transmitter in ...
Low-altitude, near-polar and near-circular orbits around Europa
(Elsevier B.V., 2012-03-01)
The dynamics of 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. The Hamiltonian considered ...
3D plausible orbital stability close to asteroid (216) Kleopatra
Recent data processing showed the existence of a difference that can reach 25 per cent for the dimensions of asteroid (216) Kleopatra between the radar observations and the light curves. We rebuild the shape of (216) ...
Stability and Evolution of Fallen Particles Around the Surface of Asteroid (101955) Bennu
(Amer Geophysical Union, 2021-01-01)
In this study, we study the dynamics of particles around Bennu. The goal is to understand the stability, evolution, and final outcome of the simulated particles around the asteroid. According to the results, the particle ...
3D stability orbits close to 433 Eros using an effective polyhedral model method
(Oxford University Press, 2014-03-01)
One of the techniques used in the past decade to determine the shape with a good accuracy and estimate certain physical features (volume, mass, moments of inertia) of asteroids is the polyhedral model method. We rebuild ...
Third-body perturbation in the case of elliptic orbits for the disturbing body
(Hindawi Publishing Corporation, 2008-01-01)
This work presents a semi-analytical and numerical study of the perturbation caused in a spacecraft by a third-body using a double averaged analytical model with the disturbing function expanded in Legendre polynomials up ...
Motion around a monopole plus ring system - I. Stability of equatorial circular orbits versus regularity of three-dimensional motion
Quasi circular orbits around prolate bodies
Recent observations of stellar occultations have revealed rings of particles around non-planetary bodies of the Solar system. These bodies are irregular and can be modelled by ellipsoids. In the context of numerical ...
Chaos around the superposition of a monopole and a thick disk
