There are several important applications for this research, such calculate the effect of lunar and solar perturbations on high-altitude Earth satellites. In this present research the goal is to study the evolution of retrograde orbits around the Earth. There is a special interest to see under which conditions a near-circular orbit remains near-circular. The existence of circular, equatorial and frozen orbits are also considered. The results are valid for any system primaries by making a time transformation that depends on the masses of the bodies involved. Several plots will show the time-histories of the Keplerian elements of the orbits involved. %@secondarydate 20021213 %E Winter, Othon Cabo, %E Prado, Antonio Fernando Bertachini de Almeida., %T A fourth-order method for the third-body perturbation: application to retrograde orbits %S Advances in space dynamics 2: applications in astronomy %@format ISBN 85-17-00005-6 %@secondarytype PRE LN %K ENGENHARIA E TECNOLOGIA ESPACIAL, perturbation, third body, orbit pertubation. %B Advances in space dynamics 2: applications in astronomy %@usergroup administrator %@group DMC-INPE-MCT-BR %C São José dos Campos %@secondarykey INPE-9539-PRE/5192 %F 10467 %2 sid.inpe.br/iris@1905/2005/08.04.02.08.27 %I INPE %P 94-111 %4 sid.inpe.br/iris@1905/2005/08.04.02.08 %D 2002 %@documentstage not transferred %A Prado, Antonio Fernando Bertachini de Almeida, %@area ETES %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S}
