Is Pluto a Planet

s Pluto a planet? This question appears so simple—clearly the answer is either
yes or no—yet the simplicity is misleading. Logically, we must know what a planet
is and determine whether Pluto fits those criteria if we are to construct a ...

A Note from the Author: On August 24, 2006, at the 26th General Assembly of the International Astronomical Union (IAU) in Prague, by a majority vote of only the 424 members present, the IAU (an organization of over 10,000 members) passed a resolution defining planet in such a way as to exclude Pluto and established a new class of objects in the solar system to be called "dwarf planets," which was deliberately designed to include Pluto. With the discovery of Eris (2003 UB313)--an outer solar system object thought to be both slightly larger than Pluto and twice as far from the Sun--astronomers have again been thrown into an age-old debate about what is and what is not a planet. One of many sizeable hunks of rock and ice in the Kuiper Belt, Eris has resisted easy classification and inspired much controversy over the definition of planethood. But, Pluto itself has been subject to controversy since its discovery in 1930, and questions over its status linger. Is it a planet? What exactly is a planet? Is Pluto a Planet? tells the story of how the meaning of the word "planet" has changed from antiquity to the present day, as new objects in our solar system have been discovered. In lively, thoroughly accessible prose, David Weintraub provides the historical, philosophical, and astronomical background that allows us to decide for ourselves whether Pluto is indeed a planet. The number of possible planets has ranged widely over the centuries, from five to seventeen. This book makes sense of it all--from the ancient Greeks' observation that some stars wander while others don't; to Copernicus, who made Earth a planet but rejected the Sun and the Moon; to the discoveries of comets, Uranus, Ceres, the asteroid belt, Neptune, Pluto, centaurs, the Kuiper Belt and Eris, and extrasolar planets. Weaving the history of our thinking about planets and cosmology into a single, remarkable story, Is Pluto a Planet? 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.

Encompassing astronomy, mythology, psychology, and astrology, Pluto offers a wealth of knowledge about our most famous dwarf planet. First observed in 1930 and once defined as the ninth and final planet in our solar system, Pluto and its discovery and reclassification throw a unique light on how we generate meaning in science and culture. This anthology, timed to appear in concordance with NASA’s New Horizons's approach to Pluto in July 2015, shows that while the astronomical Pluto may be little more than an ordinary escaped moon or tiny Kuiper Belt object, it is a powerful hyperobject, for its mythological and cultural effigies on Earth incubate deep unconscious seeds of the human psyche. Certain astronomical features pertain to Pluto in terms of its distance from the Sun, coldness, and barrenness. These also inform its mythology and astrology as befitting a planet named after the God of the Underworld. Among the issues central to this collection are the meanings of darkness, loss, grief, inner transformation, rebirth, reincarnation, and karmic revelation, all of which are associated with the astrology of Pluto. Pluto also embodies the meaning of true wealth as being nonmaterial essence instead of property, conventional accolades, ego identity, achievement. It is the marker of negative capability.

In the ten years preceding publication, the known solar system more than doubled in size. For the first time in almost two centuries an entirely new population of planetary objects was found. This 'Kuiper Belt' of minor planets beyond Neptune revolutionised our understanding of the solar system's formation and finally explained the origin of the enigmatic outer planet Pluto. This is the fascinating story of how theoretical physicists decided that there must be a population of unknown bodies beyond Neptune and how a small band of astronomers set out to find them. What they discovered was a family of ancient planetesimals whose orbits and physical properties were far more complicated than anyone expected. We follow the story of this discovery, and see how astronomers, theoretical physicists and one incredibly dedicated amateur observer came together to explore the frozen boundary of the solar system.

This book is for two groups of people: those who want to study the remote planets with amateur astronomical equipment, and those who are just interested in learning about our knowledge of the remote planets. The Remote Planets, and How to Observe them is unique in that it gives a completely up-to-date summary of our current knowledge of the remote planets, and also explains how amateur astronomers can contribute to our knowledge of the remote planets. Readers are given some inspiring examples of people who, with modest commercially-made equipment, have made important contributions to our scientific knowledge. The observational section goes into great detail, including optical and CCD photometry, occultation measurements, imaging (including stacking and enhancement techniques) and polarization measurements. There are finder charts (from 2010 to 2026), complete with two sets of star-magnitudes in an appendix (one set of magnitudes are for photoelectric photometry and the other set is for visual photometry)

Orbiting at the edge of the outer Solar System, Pluto is an intriguing object in astronomy. Since the fascinating events surrounding its discovery, it has helped increase our understanding of the origin and evolution of the Solar System, and raised questions about the nature and benefits of scientific classification. This is a timely and exciting account of Pluto and its satellites. The author uses Pluto as a case study to discuss discovery in astronomy, how remote astronomical bodies are investigated, and the role of classification in science by discussing Pluto's recent classification as a dwarf planet. Besides Pluto, the book also explores the rich assortment of bodies that constitute the Edgeworth–Kuiper Belt, of which Pluto is the largest innermost member. Richly illustrated, this text is written for general readers, amateur astronomers and students alike. Boxed text provides more advanced information especially for readers who wish to delve deeper into the subject.

For five decades after its discovery in 1930, the planet Pluto remained an enigma. However, several events during the last two decades have helped to lift the veil of mystery surrounding the ninth planet. The discovery of its satellite, Charon, in 1978 permitted occultation observations that allowed scientists to determine the size of both bodies. Astronomers also detected the presence of an atmosphere, and the Hubble Space Telescope provided views in unprecedented detail. In addition to these two fortuitous events, advances in telescopic instrumentation and computational methods led to exciting observational and theoretical discoveries. This new Space Sciences Series volume focuses on the scientific issues associated with Pluto and Charon. Fifty collaborating authors here review the latest research on the Pluto-Charon binary, from bulk properties, surfaces and interiors to atmospheric structure, composition, and dynamics. They also provide historical perspectives on Pluto-Charon research and discuss the population of the trans-Neptunian region and the origin of the Pluto-Charon binary. Also included are prefatory remarks by Pluto's and Charon's discoverers, Clyde Tombaugh and James Christy. This volume offers the most comprehensive available compendium of research work for understanding these far off members of our solar system, just at a time following dramatic developments in our knowledge but before that knowledge can be advanced by spacecraft missions.
