                         constructed in double asteroids of the solar system, assuming an 
                         irregular shape for both bodies. To make this task, a tether is 
                         attached to the surface of one of the asteroids, with a spacecraft 
                         attached in the other end. The analysis of the equilibrium points 
                         to place the tether and the stability of those solutions are made. 
                         The irregularities of the bodies, assumed to be ellipsoids, are 
                         described by the coefficients of a spherical harmonic expansion. 
                         The coefficients of this expansion are functions of the dimensions 
                         of the bodies. The equilibrium conditions are studied by searching 
                         for the situations where the forces acting in the spacecraft have 
                         a zero resultant, assuming that only the gravity of both irregular 
                         bodies are present in the system. The method is applied in the 
                         double asteroid systems (3169) Ostro and (90) Antiope, which are 
                         synchronous systems. To verify the effects of the irregularities 
                         of the bodies in the solutions, calculations are also made 
                         assuming that the bodies are spherical.",
