abstract = "The orbital dynamics around irregular shaped bodies is an actual
topic in astrodynamics, because celestial bodies are not perfect
spheres. When it comes to small celestial bodies, like asteroids
and comets, it is even more import to consider the nonspherical
shape. The gravitational field around them may generate
trajectories that are different from Keplerian orbits. Modeling an
irregular body can be a hard task, especially because it is
difficult to know the exact shape when observing it from the
Earth, due to their small sizes and long distances. Some asteroids
have been observed, but it is still a small amount compared to all
existing asteroids in the Solar System. An approximation of their
shape can be made as a sum of several known geometric shapes. Some
three-dimensional figures have closed equations for the potential
and, in this work, the formulation of a cube is considered. The
results give the mappings showing the orbits that are less
perturbed and then have a good potential to be used by spacecrafts
that need to minimize station-keeping maneuvers. Points in the
orbit that minimizes the perturbations are found and they can be
used for constellations of nanosatellites.",
