The message had seemed simple, yet it was more complex than Don could have imagined. He was being called from Earth to an alien world for reasons unknown¾save only that his life depended on it. But setting out for Mars and getting there in good shape turned out to be a lot more complicated than Don ever would have guessed possible. It was trouble enough being inexplicably hounded by Earth's secret police. But when he was hijacked by Venusian rebels, Don suddenly realized that he was trapped in the center of a war between worlds that could change the fate of the Solar System forever!

Since the publication of the popular first edition, stellar and planetary scientists have produced numerous new observations, theories, and interpretations, including the "demotion" of our former ninth planet Pluto as a dwarf planet. Covering all of these new discoveries, Planetary Science: The Science of Planets around Stars, Second Edition explains the science associated with the planets, the stars they orbit, and the interactions between them. It examines the formation, evolution, and death of stars and the properties of the Sun that influence the planets of the Solar System. Along with more problems, this second edition adds new material and improves some analytical treatments. The book consists of two main components. For students unfamiliar with stellar properties or the overall structure of the Solar System, the first part gives a general picture of the system as a whole and the interrelationships of the bodies within it. It presents an overview of the nature of stars and the Solar System as well as important results obtained by scientific analysis. The second component is a set of 43 appendices describing the majority of the underlying science required to explain the main features of the Solar System. These appendices cover a variety of specialized topics, from mineralogy to the mechanical interactions of radiation and matter. End-of-chapter problems give students a quantitative understanding of stellar and solar system phenomena. The text shows how useful estimates of various quantities can be made even when characteristics of the system are not known with any precision. While the problems can be completed with a hand calculator, students are encouraged to use the Fortran computer programs provided on the book’s CRC Press web page. Avoiding excessive details, this textbook offers a comprehensive account of stellar and planetary topics. It is suitable for students from a range of disciplines, including astronomy, geology, and earth sciences. The book provides students with an understanding of the nature of the Solar System and the influences that govern its behavior, helping them develop an appreciation of the forces that can influence our planet in the future.

An introduction to the laws of celestial mechanics and a step-by-step guide to developing software for direct use in astrophysics research. This book offers both an introduction to the laws of celestial mechanics and a step-by-step guide to developing software for direct use in astrophysics research. It bridges the gap between conventional textbooks, which present a rigorous and exhaustive exposition of theoretical concepts, and applying the theory to tackle real experiments. The text is written engagingly in dialogue form, presenting the research journey of the fictional Alice, Bob, and Professor Starmover. Moving Planets Around not only educates students on the laws of Newtonian gravity, it also provides all that they need to start writing their own software, from scratch, for simulating the dynamical evolution of planets and exoplanets, stars, or other heavenly bodies.

Profiles each of the planets in Earth's solar system, including Pluto, Ceres, Eris, Haumea, MakeMake, the sun, the Oort cloud, comets, and more.

Planets in Play is the first foundational book that lets the reader reimagine his or her inner life through the self-exploratory language of astrology. Author Laurence Hillman-a widely respected astrologer with a loyal following and a formidable online presence-reconnects the planets with the character traits given them by the ancients. Whether one accepts astrology as being "real," its language and concepts can go a long way toward helping us see the archetypes that play on our lives. In observing the strengths, weaknesses, and character traits of each planet and zodiac sign, readers will receive a toolbox filled with instruments with which to newly understand their lives. The reader will then be able to make more conscious choices about how he or she is living out these different aspects. To that end, Hillman provides specific tactics and highly practical ideas of how to expressly nourish or minimize these tendencies through choice of behavior, lifestyle, and personal surroundings. Case examples, stories, and anecdotes run throughout the book to demonstrate and ease this process. In its appendices, Planets in Play provides a guide in how to get a quality astrological reading, with an emphasis on one's dominant archetypes. In addition, Hillman offers a basic grounding in astrology for those readers, therapists, or counselors who wish to learn how the ancient art works at a psychological level without necessarily committing themselves to its study.
