Not within the solar system, but within the stellar neighborhood. If you construct a voronoi volume around the sun, then very roughly you'd expect 5 solar masses of dark matter in that volume. But that is a HUGE volume, on the order of tens of thousands of AU on a side. In the area we can directly observe (via orbits of bodies we can see), the fraction of dark matter comes out to like one part in a trillion or thereabouts.
