                         between a planet and a group of particles. The mathematical model 
                         includes the presence of the atmosphere of the planet. This cloud 
                         is assumed to be created by the passage of the spacecraft in the 
                         atmosphere of the planet, which can cause the explosion of the 
                         spacecraft. The system is assumed to be formed by the Sun, the 
                         planet, and the spacecraft that explodes and becomes a cloud of 
                         particles. The Sun and the planet are assumed to be in circular 
                         orbits and the motion is planar. The equations of motion are the 
                         ones given by the circular planar restricted three-body problem 
                         combined with the forces given by the atmospheric drag. In the 
                         numerical simulations, the planet Jupiter is the celestial body 
                         used for the close approaches. The initial positions and 
                         velocities of the spacecraft and the particles are specified at 
                         the periapsis, because it is assumed that this is the point where 
                         the explosion occurs.",
