Abstract: We point out that by comparing the total mass in gravitational units of theearth-moon system, as determined by lunar laser ranging, with the sum of thelunar mass as independently determined by its gravitational action onsatellites or asteroids, and the earth mass, as determined by the LAGEOSgeodetic survey satellite, one can get a direct measure of the mass ofearth-bound dark matter lying between the radius of the moon-s orbit and thegeodetic satellite orbit. Current data show that the mass of such earth-bounddark matter must be less than $4 \times 10^{-9}$ of the earth-s mass.
