                         Swing-By maneuvers. Our goal is to simulate a large variety of 
                         initial conditions for those orbits and study them according to 
                         the effects caused by this close approach. The practical 
                         importance of this topic is to allow mission designers to explore 
                         close approaches with planets in a more realistic model, as well 
                         as to take advantage of the atmospheric effects, when it is 
                         possible. We use the well-known planar restricted circular 
                         three-body problem plus atmospheric drag as our model. We 
                         integrate numerically the equations of motion forward and backward 
                         in time, until the spacecraft is in a distance that we can 
                         consider far enough from the planet's effect and consider the 
                         system formed by the Sun and the spacecraft as a two-body system. 
                         At these two points we can use the two-body celestial mechanics to 
                         compute energy, angular momentum and the Jacobian constant before 
                         and after the close approach.",
