Abstract
Analyses of laser ranges to the Moon provide increasingly stringent limits on any violation of the equivalence principle (EP); they also enable several very accurate tests of relativistic gravity. These analyses give an EP test of . This result yields a strong equivalence principle (SEP) test of . Also, the corresponding SEP violation parameter is , where and both and are post-Newtonian parameters. Using the Cassini , the result yields . The geodetic precession test, expressed as a relative deviation from general relativity, is . The search for a time variation in the gravitational constant results in ; consequently there is no evidence for local () scale expansion of the solar system.
