ResumoAsteroids are rotating bodies with asymmetric distribution of mass, which makes the gravitational field around them different from spherical bodies. In order to more accurately study the gravitational field around these objects, it is necessary to have a physical model. To simplify the model of an asteroid, it is common to use approximations to simple shapes such as ellipsoids. However, this may lead to an imprecise model, especially when the asteroid has a very asymmetric shape. Thus, a new methodology developed to model the gravitational field of the asteroids is presented, called Mascon-layer model. It consists in using a polyhedron shape model, which is built using observational data, thus giving a good approximation of the real shape of the object. This shape model is then transformed into layers of mass concentrations. The gravitational potential is obtained using the new model, and then applied to analyze very close orbits on the collision boundary, and very distant orbits on the verge of escaping the sphere of influence of the asteroid's gravitational field. Orbital maneuvers, using continuous low thrust in closed loop, were also performed. One of the advantages of the methodology developed is that it is possible to use a simpler approach, requiring less computational effort, but still using a reliable source for the shape model.
