Description
The meaning of the word "planet" has changed over time as new objects in our solar system have been discovered. In 2006, the International Astronomical Union redefined the term to exclude Pluto, but controversy surrounding its status persists. David Weintraub explores the historical, philosophical, and astronomical background that led to this change, tracing the evolution of the concept of a planet from antiquity to the present day. He examines the discovery of Eris, an object similar in size to Pluto, which has sparked debate about the definition of planethood. Through lively and accessible prose, Weintraub provides a nuanced understanding of the complexities surrounding Pluto's status as a planet, allowing readers to form their own opinion on the matter.
