High precision planet orbital data extracted from direct observation, spacecraft explorations, and laser ranging techniques enable to constrain the maximal dark matter density of a spherical halo centered around the Sun. If we assume a halo profile with a power-law dependence in the heliocentric distance, the maximal density at Earth's location is of the order 10(5) GeV/cm(3). Moreover, this value shows only a mild dependence on the slope of the halo profile, taken between 0 and -2. This bound competes with that obtained from the perihelion precession limits.
