Is Pluto a Planet?: A Historical Journey Through the Solar System [Englisch] [Gebundene Ausgabe]

Its status ambiguous ever since its discovery in 1930, hapless Pluto received an insult to its dignity when the International Astronomical Union (IAU) demoted it from planethood in August 2006. Weintraub, though, will not be stampeded as he methodically considers the historically evolving definitions of a planet. An astronomy professor, he walks through inductions and expulsions from the planetary hall of fame that have accompanied the replacement of the geocentric solar system by the heliocentric one. With fine clarity, Weintraub explains how Kepler's laws, Galileo's discovery of Jupiter's moons, and Newton's laws lent mathematical definition to planets and gave astronomers the inspiration and tools to find more. After full-bodied Uranus and Neptune, tiny Pluto on its eccentric orbit was a dud, but surely a planet, no? That assertion wobbled under recent recognition that Pluto inhabits a neighborhood of similarly icy spheres, the Plutinos, which Weintraub descriptively catalogs. His survey of planetary discovery in hand, Weintraub delivers his answer to the title's question to cap an accessible, informative presentation of planetary astronomy. Gilbert Taylor

David Weintraub sets the debate in its full context, and his views will be of interest to anyone who wants to know how our view of the universe around us has changed over time. -- Martin Ince, Times Higher Education Supplement Vanderbilt astronomer Weintraub places the Pluto controversy in context in his judicious, lively account of the development of our solar system and the evolution of the meaning of the word planet... Weintraub effectively shows that Pluto is a planet by most definitions, but so are several other objects in the Kuiper asteroid belt. Weintraub's provocative, engaging study points to the richness and complexity of our solar system and its many possible planets. -- "Publishers Weekly Well told... "Is Pluto a Planet?" ... provides a readable historical account of our knowledge of the Solar System and the concept of what has been considered to be a planet... Towards the end of this interesting book, Weintraub surprisingly concludes, despite the close analogy between the discovery of the asteroid and Kuiper belts, that we should retain Pluto as a planet by using three physical parameters of orbital characteristics, mass and roundness. -- Stuart Ross Taylor, Nature Weintraub discusses how the concept of planet has changed. He describes the rises and falls in the number of planets recognized in our solar system--changes that lead him to term Pluto 'the fourth ninth planet.' Although readers may not accept Weintraub's answer to the titular question, they will find his thought-provoking account provides ample information for supporting a variety of positions in the continuing debate. -- "Science A fascinating, accessible, and eminently readable historical introduction to the development of the planetary ideal. -- David W. Hughes, Observatory This book takes a sensible historical (rather than hysterical) perspective... Is Pluto a Planet? is a comprehensive and desperately needed exploration of the subject and accessible to those without a prior knowledge of astronomy. -- Steve Ringwood, Astronomy Now Few topics in planetary science have ignited as much public debate and outright acrimony as the recent decision by the International Astronomical Union to revoke Pluto's planetary status...This kind of fervor makes David A. Weintraub's Is Pluto a Planet? particularly timely in that it provides some much-needed perspective on the battle over the meaning of the term 'planet,' a battle that, as we often forget, has been going on as long as astronomy itself...[T]here is much to recommend in Is Pluto a Planet? Weintraub's history of the term 'planet' is well told and interesting, and the narrative successfully walks readers through many of the pros and cons of different planet definitions. It puts the current debate into context and demonstrates how the acceptance of the new over the old in astronomy is driven or deterred as much by human foibles as by new information... -- William F. Bottke, Physics Today Weintraub's discussion of planetary discovery and categorization puts the brouhaha over Pluto's planetary status into perspective. -- Carolyn Collins Petersen, Sky & Telescope David W. Weintraub's Is Pluto a Planet? A Historical Journey through the Solar System ... traces the history of how 'planet' has been defined over the centuries. -- "Library Journal Book Blog Its status ambiguous ever since its discovery in 1930, hapless Pluto received an insult to its dignity when the International Astronomical Union (IAU) demoted it from planethood in August 2006. Weintraub, though, will not be stampeded as he methodically considers the historically evolving definitions of a planet... His survey of planetary discovery in hand, Weintraub delivers his answer to the title's question to cap an accessible, informative presentation of planetary astronomy. -- Gilbert Taylor, Booklist Is Pluto a Planet? is ... [an] exceptional new book...The writing is both lively and precise, conveying both historical detail and scientific explanation in clear, understandable terms. His style respects the reader's intelligence without being either didactic or superior, and the exploration of discovery remains compelling chapter after chapter. -- Howard Shirley, BookPage Weaving the history of our thinking about planets and cosmology into a single, remarkable story, this book is for all those who seek a fuller understanding of the science surrounding both Pluto and the provocative recent discoveries in our outer solar system. -- "Lunar and Planetary Information Bulletin This excellent exploration of the history of planetary astronomy provides readers with enough information to attempt their own answer. The IAU will undoubtedly consider the definition of planet in 2009; all those voting in 2006 should have considered the issues in this book... Highly recommended. -- "Choice Weintraub argues that Pluto, and many of those objects, should be called planets. He lost that argument, but that doesn't take away from the book. He lays out in clear details the history of the discovery of the solar system. He discusses the mathematics in clear and concise detail so we don't get lost. And he covers all the arguments and gives a clear picture of learned humans struggling to understand the world around them. -- Terry England, Santa Fe New Mexican Students and friends used to ask, 'What do you really know about UFOs?' Now they ask, 'What about Pluto?' Weintraub explains not only how such things are decided, but also how we have come to understand the structure of our solar system...For an investment in a well-written solar system and intellectual history, we recommend Is Pluto a Planet? -- Bruce L. Dietrich, Planetarian The author concentrates on providing a detailed historical background to the Pluto issue by tracing the way our view of what constitutes a planet has evolved since the Mayans and the Babylonians began to observe the heavens... Readers who enjoy immersing themselves in the history of astronomy, however many times they've read of Aristotle, Copernicus, and Kepler, will like this book. -- Mark Williamson, Space Times
