                         long-lasting concern is finally being addressed: the deflection of 
                         potentially hazardous objects (PHOs). Most recently, the first 
                         mission of this kind was launched by NASAthe Double Asteroid 
                         Redirection Test (DART). Nevertheless, it is estimated that a 
                         great number of these PHOs are unattainable by means of current 
                         chemical propulsion systems. With that in mind, this study 
                         proposes the development of a heuristic technique for the search 
                         of interception trajectories with the use of solar sails and its 
                         application in determining a set of possible trajectories to 
                         intercept hazardous asteroids. As a case study, a hybrid mission 
                         inspired by the DART mission is proposed by using a solar sail as 
                         means of propulsion after the initial chemical combustion. The 
                         dynamics consider a model of the solar radiation pressure 
                         acceleration as a function of the orientation of the sail. In 
                         turn, the orientation is defined by the application of the 
                         developed heuristic technique with the goal of defining 
                         alternative trajectories compared to the original mission. These 
                         trajectories result in different impact conditions and mission 
                         durations. Although the use of solar sails breaks the symmetry in 
                         the solutions, the results obtained offer the possibility of fuel 
                         economy or even better deflection results by the achievement of 
                         greater impact energy with the hazardous objects.",
