The current plan of activities involve the stability around the triple system 2001SN263, as well as the formation of bodies similar to Alpha. With relation to the stability, the novelties are the inclusion of the perturbations due to the solar radiation pressure and the gravitational potential assuming the irregular shape of the bodies. With respect to the shape of Alpha, the larger body of the triple system, it was identified a set of asteroids with this kind of format ("spinning top"). In this plan is proposed to study the conditions that can generate this kind of format, taking into account the effects due to the rotation and/or collisions with other bodies. (AU)
