A standard reference that provides, in accessible form, selected critical data for professional and student solid Earth and planetary geophysicists. It represents the third version of the popular "Handbook of Physical Constants" (the first was published in 1942, the second in 1966). The present version reflects the enormous growth of scientific knowledge of the Earth and planets since 1966, spurred by the discovery and verification of plate tectonics and the systematic exploration of the solar system.
