Is Pluto a planet? : a historical journey through the solar system

Open All Close All

  • "With the discovery of 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, 2003 UB313 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? [This book] 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 [the book, the author] 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 2003 UB313, and extrasolar planets. Weaving the history of our thinking about planets and cosmology into a single, remarkable story, [the 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.-Dust jacket."
  • "Chronicles the history of "planethood," tracing the evolution of our definition of planets and the debates over that definition as our knowledge of the universe and the bodies that inhabit it has grown. Chronicles the current state of those debates which have been fueled by the discovery of 2003 UB313, an outer solar system object which is thought to be slightly larger than Pluto, thus destabilizing Pluto's status as a planet and calling into question our definition of planets in general."
