Some results from a reduction of radar, laser and optical observations of the inner planets and of the moon.
Abstract
Radar, laser, and optical data on the motions of the inner planets and the moon were analyzed on the basis of an improved theory involving the numerical integration of the equations of motion of the large planets (excluding Pluto) and the moon. An improved determination of the lunar ephemeris is discussed, and the present results are used to examine the hypothesis of the secular decrease of the value of the gravitational constant.
