Investigating the Moon’s Motion by Laser Rangingterminations have been especially interesting because radar measures distance (albeit in light-seconds rather than in meters) more directly than and independently of the classical astronomical triangulation methods. In addition to yielding precise distances, detailed examination of the reflected ene

Cassini’s Second and Third LawsIn 1693 G. D. Cassini published the three following empirical laws on the Moon’s rotational motion:

The Moon’s Mechanical EllipticityIn a discussion of problems connected with the Moon’s physical libration one cannot fail to pay particular attention to the quantity ., the so-called Moon’s mechanical ellipticity.

Laser Measurement of Earth-Moon Distance and Selenographye then, there has been practically no interruption in observation of the Moon by radar, which has brought us a great deal of important information, including, in particular, a new lunar parallax value (cf. .., 1965).
