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 …

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 …

The present paper studies the lifetime of orbits around a moon that is in orbit around its
mother planet. In the context of the inner restricted three-body problem, the dynamical model …

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 …

AS IS well known, the long-term dynamics of a probe around a celestial body (primary body)
can be investigated by performing an average of the disturbing function, which is generally …

An important aspect concerning the dynamics of a probe around a natural satellite is
represented by the probe lifetime. In fact, the science orbits, usually characterised by low …

It is desirable to design low-altitude and near-polar science orbits for missions to Galilean
moons. However, the long-term perturbation from a distant perturber may lead such a kind of …

In this paper, the feasibility of exploiting the Sun's gravitational force to design the final
phase (capture and orbit circularisation) to Mercury with a low propellant consumption has …

SECULAR perturbations caused by a third-body attractor were widely studied in the past. In
the 1960s, Lidov and Kozai described the mathematical model for the orbital evolution of a …

An analysis of the orbital motion of artificial satellites around Mercury is presented taking into
account its non-sphericity (J 2, J 3, C 22) and the perturbation of the third body. The …
