Equivalence of Active and Passive Gravitational Mass Tested with Lunar Laser Ranging

Abstract

LLR measures the distance between observatories on Earth and retro-reflectors on Moon since 1969. In this paper, we study the possible violation of the equality of passive and active gravitational mass ($m_a/m_p$), for Aluminium (Al) and Iron (Fe), using LLR data. Our new limit of $3.9\cdot 10^{-14}$ is about 100 times better than that of Bartlett and Van Buren [1986] reflecting the benefit of the many years of LLR data.
