For years, students used the mnemonic My Very Eager Mother Just Served Us Nine Pizzas to remember the names of the planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. But on August 24, 2006, the phrase became obsolete with the announcement that Pluto was no longer considered a planet. How did this happen? What does it mean to be a planet, and who decides? And what is Pluto now? Full-color photographs and illustrations. Glossary. Suggested additional reading. Index.
