'This book provides a wonderful and very detailed guide for those interested in comparing observations with Einstein's theory and the many proposed alternatives. Written in a very readable and accessible manner, it is an indispensable guide to comparing theoretical gravitational predictions with the most recent data coming from celestial observations provided by satellites, space probes, and telescopes. I highly recommend it to anyone interested in a very practical handbook for comparing theory and observations.' Jim Isenberg, Professor Emeritus, University of Oregon
