Planetary dynamics



Under planetary dynamics we include precise range determinations and improvements in the ephemerides, new ideas and tests of general relativity, tidal evolution of planetary spins and the orbit of the moon, commensurabilities in the solar system, and several selected topics dealing with unusual or long standing problems. Specific techniques of celestial mechanics are not included except as direct applications to the above subjects. References that provide observational or theoretical background to the various topics even though not pertaining directly to planetary dynamics are included in the bibliography.
