The lifetime of a probe moving at low altitude around Europa is strictly correlated, other than
to the effects due to the interaction with Jupiter's magnetic field, but also to the eccentricity …

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 …

As the most volcanically active celestial body in the Solar System, Io is a natural satellite of
Jupiter due to its proximity to the planet and the fact that it is in mean motion resonance …

Considering the growing interest in sending probes to the natural satellite Titan, our work
aims to investigate and map natural orbits around this moon. For that, we use mathematical …

Let us consider the restricted three-body problem. Analysis of the orbital motion of a
spacecraft around planets or moons is presented taking into account the nonsphericity of the …

Orbiting the primary of a binary asteroid system is extremely challenging due to the
perturbative effects of the primary's nonspherical gravity and the secondary's close-proximity …

In the field of the orbital perturbations dealt with an approach based on the mean orbital
elements theory, the outer third-body gravitational attraction has been widely investigated …

In this work, two dynamical models are formulated to describe the secular dynamics of
navigation satellites moving in the medium Earth orbit (MEO) and geosynchronous orbit …

Close polar and circular orbits are of great interest for the exploration of natural satellites.
There are still no studies in the literature investigating orbits around Titania, the largest …

It is in the interest of astronomy and engineering to find orbits for spacecraft that allow a
good observation of the orbited body and, at the same time, to reduce expenses with fuel …
