【 摘 要 】

We explore the possibility to constrain the dark matter (DM) sub-structure properties, mass and distribution, at sub-galactic scales, by considering the dynamics of some astrophysical system under the dynamical influence of such sub-structure. We present preliminary results discussing the sensitivity of the Solar System dynamics, and dSphs wide binaries abundance, to the small scale DM distribution.
