Several non-functional objects are orbiting around the Earth and they are called space
debris. In this work, we investigate the process of space debris mitigation from the GEO …

A novel methodology is proposed to design the transfers from halo orbits to low-eccentricity,
high-inclination frozen orbits around planetary moons, with applications to the Jupiter …

In the exploration of celestial bodies, including planets, moons, and asteroids, it is useful to
identify stable orbits in which the orbital elements remain, on average, constant (referred to …

The semi-analytical model (based on the averaging technique) for long-term orbital
evolution has proven to be useful in both astrophysical and astrodynamical contexts. In this …

UNLIKE J2 perturbations, third-body perturbations alter an orbit's shape rather than just its
orientation. The eccentricity and inclination may exhibit significant oscillations. In 1959 …

The infinite spin problem is a problem concerning the rotational behavior of total collision
orbits in the $ n $-body problem. The question also makes sense for partial collision. When …

Orbital debris, or space debris, consists of man-made objects that have been launched into
space but no longer serve any useful purpose. This debris, which includes defunct satellites …

To contribute to space debris mitigation studies, in this work, we consider the effects of
natural orbital perturbations and the resonance effect to excite the orbital elements of the …

A dinâmica de uma sonda sob efeito do achatamento do planeta hospedeiro, pressão de
radiação solar (PRS) e ainda de um terceiro corpo, é um antigo problema, exaustivamente …
