                         particles. It is assumed that the dynamical system is formed by 
                         two main bodies in circular orbits and a cloud of particles in 
                         planar motion. The goal is to study the change of the orbit of 
                         this cloud after the close approach with the planet. It is assumed 
                         that all the particles have semi- major axis a ñ Da and 
                         eccentricity e ñ De before the close approach with the planet. It 
                         is desired to known those values after the close approach.",
