Analytical direct planetary perturbations on the orbital motion of satellites
An analytical expansion of the disturbing function arising from direct planetary perturbations on the motion of satellites is derived. As a Fourier series, it allows the investigation of the secular effects of these direct ...
FROZEN ORBITS AROUND EUROPA
(World Scientific Publ Co Pte Ltd, 2012-10-01)
Low-altitude, near-polar orbits are very desirable for scientific missions to study the natural satellites of the planets of the Solar System, such as Europa, that is one of the natural satellites of Jupiter. The problem ...
A Study of Single- and Double-Averaged Second-Order Models to Evaluate Third-Body Perturbation Considering Elliptic Orbits for the Perturbing Body
(Hindawi Publishing Corporation, 2013-01-01)
The equations for the variations of the Keplerian elements of the orbit of a spacecraft perturbed by a third body are developed using a single average over the motion of the spacecraft, considering an elliptic orbit for ...
Gravitational effects of Nix and Hydra in the external region of the Pluto-Charon system
Two new companions to the Pluto-Charon binary system have been detected in 2005 by Weaver et al. These small satellites, named Nix and Hydra, are located beyond Charon's orbit. Although they are small when compared to ...
Planetary Satellite Orbiters: Applications for the Moon
(Hindawi Publishing Corporation, 2011-01-01)
Low-altitude, near-polar orbits are very desirable as science orbits for missions to planetary satellites, such as the Earth's Moon. In this paper, we present an analytical theory with numerical simulations to study the ...
Perturbations to Saturn's F-ring strands at their closest approach to Prometheus
The strange morphology of the F ring of Saturn is thought to be caused by the perturbing effects of two close satellites, Prometheus and Pandora. The F ring and the satellites also experience periodic close encounters as ...
ORBITAL PERTURBATIONS OF THE GALILEAN SATELLITES DURING PLANETARY ENCOUNTERS
(Iop Publishing Ltd, 2014)
Dynamical capture in the Pluto-Charon system
This paper explores the possibility that the progenitors of the small satellites of Pluto got captured in the Pluto-Charon system from the massive heliocentric planetesimal disk in which Pluto was originally embedded into. ...
Effects of the Eccentricity of a Perturbing Third Body on the Orbital Correction Maneuvers of a Spacecraft
(Hindawi Publishing Corporation, 2014)
The strands of the F ring disturbed by its closest satellites
(Elsevier B.V., 2006-01-01)
Some Voyager images showed that the F ring of Saturn is composed of at least four separate, non-intersecting, strands covering about 45 degrees in longitude. According to Murray et al. [Murray, C.D., Gordon, M., Giuliatti ...
