             abstract = "It is widely accepted that knowing the composition and the orbital 
                         evolution of asteroids might help us to understand the process of 
                         formation of the Solar system. It is also known that asteroids can 
                         represent a threat to our planet. Such an important role has made 
                         space missions to asteroids a very popular topic in current 
                         astrodynamics and astronomy studies. Taking into account the 
                         increasing interest in space missions to asteroids, especially to 
                         multiple systems, we present a study that aims to characterize the 
                         stable and unstable regions around the triple system of asteroids 
                         (45) Eugenia. The goal is to characterize the unstable and stable 
                         regions of this system and to make a comparison with the system 
                         2001 SN263, which is the target of the Advanced Spaceborne Thermal 
                         Emission and Reflection Radiometer (ASTER) mission. A new concept 
                         was used for mapping orbits, by considering the disturbance 
                         received by the spacecraft from all perturbing forces 
                         individually. This method has also been applied to (45) Eugenia. 
                         We present the stable and unstable regions for particles with 
                         relative inclination between 0° and 180°. We found that (45) 
                         Eugenia presents larger stable regions for both prograde and 
                         retrograde cases. This is mainly because the satellites of this 
                         system are small when compared to the primary body, and because 
                         they are not close to each other. We also present a comparison 
                         between these two triple systems, and we discuss how these results 
                         can guide us in the planning of future missions.",
