abstract = "The goal of this research is to study close approaches between the
Moon and a cloud of particles. The system is formed by two main
bodies (the Earth and the Moon) and it is assumed that they are in
circular orbits. The cloud of particles is moving under their
gravitational attraction. The motion is assumed to be planar for
all the particles and the dynamics given by the patched-conic
approximation is used, which means that a series of two-body
problems are used to generate analytical equations that describe
the problem. The main obejctive is to understand the change of the
orbit of this cloud of particles after the close approach with the
Moon. It is assumed that all the particles that belong to the
cloud have semi-major axis a ± da and eccentricity e ± de before
the close approach with the Moon, such that the particles are
inside a circle (in the semi-major axis-eccentricity plane) with
center in the center of mass of the cloud. It is desired to known
those values after the close approach.",
