  Didymos and Dimorphos are primary and secondary, respectively, asteroids who
compose a binary system that make up the set of Near Earth Asteroids (NEAs).
They are targets of the Double Asteroid Redirection Test (DART), the first test
mission dedicated to study of planetary defense, for which the main goal is to
measure the changes caused after the secondary body is hit by a kinect
impactor. The present work intends to conduct a study, through numerical
integrations, on the dynamics of massless particles distributed in the vicinity
of the two bodies. An approximate shape for the primary body was considered as
a model of mass concentrations (mascons) and the secondary was considered as a
massive point. Our results show the location and size of stable regions, and
also their lifetime.
