If primordial black holes (PBHs) of asteroidal mass make up the entire dark matter they could be detectable through their gravitational influence in solar system. In this work, we study perturbations that PBHs induce on orbits planets. Detailed numerical simulations system, embedded a halo PBHs, are performed. Using Earth-Mars distance as an observational probe, show below current detection limits and thus not directly constrained by system ephemerides. We estimate improvement measurement accuracy more than order magnitude or extraction signals well noise level required to detect foreseeable future.
