Book Description
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.

Book Description
The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of adding one more planet to our solar system, Brown’s find ignited a firestorm of controversy that culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about. A heartfelt and personal journey filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever imagined exploring the universe—and who among us hasn’t?

Book Description
For Pluto, summer has always started with a trip to the planetarium. It’s the launch to her favorite season, which also includes visits to the boardwalk arcade, working in her mom’s pizzeria, and her best friend Meredith’s birthday party. But this summer, none of that feels possible. A month before the end of the school year, Pluto’s frightened mom broke down Pluto’s bedroom door. What came next were doctor’s appointments, a diagnosis of depression, and a big black hole that still sits on Pluto’s chest, making it too hard to do anything. Pluto can’t explain to her mom why she can’t do the things she used to love. And it isn’t until Pluto’s dad threatens to make her move with him to the city—where he believes his money, in particular, could help—that Pluto becomes desperate enough to do whatever it takes to be the old Pluto again. She develops a plan and a checklist: If she takes her medication, if she goes to the planetarium with her mom for her birthday, if she successfully finishes her summer school work with her tutor, if she goes to Meredith’s birthday party . . . if she does all the things that “normal” Pluto would do, she can stay with her mom in Jersey. But it takes a new therapist, a new tutor, and a new (and cute) friend with a checklist and plan of her own for Pluto to learn that there is no old and new Pluto. There’s just her.

Book Description
In support of Pluto-the cutest and most unfairly treated planet Pity poor Pluto: It's a planet that was discovered because of a mistake, a planet that turned out not to be a planet at all, thanks to a still-disputed decision made in 2006. And yet, Pluto is the planet best-loved by Americans, especially children, one that may have contained the building blocks of life billions of years ago and may well serve as life's last redoubt billions of years from now. In The Case for Pluto, award-winning science writer Alan Boyle traces the tiny planet's ups and downs, its strange appeal, the reasons behind its demotion, and the reasons why it should be set back in the planetary pantheon. Tells the compelling story of Pluto's discovery and how it became a cultural icon Makes the case for Pluto as planet, countering the books that argue against it Comes in a small, friendly package — just like Pluto — and features a handsome design, making it a great gift The Case for Pluto is the must-read tale of a cosmic underdog that has captured the hearts of millions: an endearing little planet that is changing the way we see the universe beyond our backyard. Alan Boyle is MSNBC.com’s science editor and the award-winning blogger behind Cosmic Log. He’s been a talking head on NBC’s The Today Show and the MSNBC cable channel, holding forth on scientific subjects ranging from the chances of an asteroid Armageddon to the 3-D wizardry behind the “Harry Potter” movies. But he writes better than he talks.

Book Description
The amazing science behind the search for Earth-like planets Ever since Carl Sagan first predicted that extraterrestrial civilizations must number in the millions, the search for life on other planets has gripped our imagination. Is Earth so rare that advanced life forms like us—or even the simplest biological organisms—are unique to the universe? How to Find a Habitable Planet describes how scientists are testing Sagan's prediction, and demonstrates why Earth may not be so rare after all. James Kasting has worked closely with NASA in its mission to detect habitable worlds outside our solar system, and in this book he introduces readers to the advanced methodologies being used in this extraordinary quest. He addresses the compelling questions that planetary scientists grapple with today: What exactly makes a planet habitable? What are the signatures of life astronomers should look for when they scan the heavens for habitable worlds? In providing answers, Kasting explains why Earth has remained habitable despite a substantial rise in solar luminosity over time, and why our neighbors, Venus and Mars, haven't. If other Earth-sized planets endowed with enough water and carbon are out there, he argues, chances are good that some of those planets sustain life. Kasting describes the efforts under way to find them, and predicts that future discoveries will profoundly alter our view of the universe and our place in it. This book is a must-read for anyone who has ever dreamed of finding other planets like ours—and perhaps even life like ours—in the cosmos. In a new afterword, Kasting presents some recent breakthroughs in the search for exoplanets and discusses the challenges facing space programs in the near future.

Book Description
The New York Times bestseller: "You gotta read this. It is the most exciting book about Pluto you will ever read in your life." —Jon Stewart When the Rose Center for Earth and Space at the American Museum of Natural History reclassified Pluto as an icy comet, the New York Times proclaimed on page one, "Pluto Not a Planet? Only in New York." Immediately, the public, professionals, and press were choosing sides over Pluto's planethood. Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.
