Tracking data fromt the lunar orbiters have been analyzed for information regarding Moon's gravity field. These preliminary results include values of a set of harmonic coefficients throlugh degree 4 in the tesserals and degree 8 in the zonals. Implications regarding Moon's mass distribution are discltssed: one implicationt is that Moon is nearly homogeneous.
