Scientific American series.
This serviceable, occasionally lively introduction to orbital mechanics explains Earth's rotation, revolution, and the history of discoveries, along with information about galaxies and the expanding universe. Clear explanations of terms including precession, analemma, and Cepheid variables are extended with captioned photos and sidebars.
