Abstract Solar system small bodies, as asteroids, comets and some satellites, have a shape very distinct from a spherical one. Some of them had their shape obtained by spacecraft images or through data from radiotelescopes from Earth.In general, the shape of these bodies is reproduced in terms of a set of polyhedra with triangular faces, where are know all of their vertices. Assuming a value for the body's density and considering it to be homogeneous, it is possible to determine its gravitational potential. That is made through numerical integration based on the faces and vertices that compose the body. Following that approach were written computational routines that allow to dinamically explore the neighborhood around these small bodies. In particular, obtaining dynamical characteristics such as zero velocity curves, equilibrium points, stability regions, etc. The main goals of this project are:i) to explore the gravitational field around small bodies;ii) to determine the location of equilibrium points and analyze their linear stability. | |
