Originally published in 1979, this was a comprehensive source and textbook on asteroids by 70 authors covering exploration, composition, evolution, and the interrelations with other small solar system bodies. Also includes an extensive file of all known asteroid parameters including magnitudes, colors, proper elements and compositional types.

This sourcebook brought together our knowledge about asteroids, based on a gather during the week of March 8-11, 1988 with move than 160 scientists from 14 countries who gathered in Tucson for the Asteroids II conference.

Asteroids II is not a sequel, per se, to the 1979 book Asteroids. It offered a fresh treatment intended to stand on its own as a complete description of the current understanding of the field. It was published in December 1989. The work showcased a large international collaboration, a sign of an active and growing discipline.

In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.

Originally published in 1979, at the time of it's publication this work was a unique source book on star formation and the origin of planetary systems from some 35 distinguished authors. Topics include the formation of stars from the cloudy to the stellar to the planetary state. Special emphasis on stars believed capable of producing planets. This foundational work sought to define a new discipline and set the course for the University of Arizona Space Science series.
