Abstract

The objective of this work is to study models and methods for the calculation of spatial trajectories around the lagrangian points of a multiple asteroid system. It will be studied and compared different strategies involving this type of orbit. The main idea is to determine the exact positions of the equilibrium points of the equations of motion for an artificial satellite that travels around a triple asteroid system, in particular the asteroid 2001SN263. This asteroid is the main target of the mission ASTER, which has been studied in Brazil and aims to send a spacecraft to an asteroid triple as a way to develop cutting-edge technologies in this area, as well as make important scientific studies in the field of astronomy. Several mathematical models are considered, starting with the circular restricted planar three-body problem and then proceeding to more elaborate models that consider elliptical and/or three-dimensional orbits. The need for other models will be evaluated by this study, such as the inclusion of the restricted problem of four bodies, flattening of the main body, and consideration of elliptic and/or inclined orbits for the two smaller bodies.
