Studying the lifetime of orbits around Moons in elliptic motion
(2016-10-01)
The main goal of the present paper is to study the lifetime of orbits around moons that are in elliptic motion around their parent planet. The lifetime of the orbits is defined as the time the orbit stays in orbit around ...
Third-body perturbation in the case of elliptic orbits for the disturbing body
(2008-12-01)
In the present work it is presented a semi-analytical and a 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 ...

Este trabalho tem como objetivo apresentar uma revisão bibliográfica e desenvolver propostas didáticas para entender algumas das metodologias empregadas para determinar a esfericidade da Terra e seu movimento orbital. Para ...
Some orbital characteristics of lunar artificial satellites
(Springer, 2010-12-01)
In this paper we present an analytical theory with numerical simulations to study the orbital motion of lunar artificial satellites. We consider the problem of an artificial satellite perturbed by the non-uniform distribution ...

A semi-analytical approach to study resonances effects on the orbital motion of artificial satellites
(2013-01-01)
A semi-analytical approach is proposed to study resonances effects on the orbital motion of artificial satellites or space debris orbiting the Earth. Applying successive Mathieu transformations, the order of dynamical ...
