Pluto The Dwarf Planets

In 2006, Pluto was reclassified as a dwarf planet. Small, rocky dwarf planets make their home on the outer edges of the solar system. Scientists use telescopes to study Pluto and the dwarf planets as they orbit the Sun. Their fascinating findings are on display in this informative title about some of the solar system’s most far-away objects!

Describes the physical characteristics and movements of the smallest bodies of rock and ice that are in rotation around the Sun, and are known as dwarf planets.

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?

In the cold, dark, lonely environment of the outer reaches of the Solar System lies Pluto, the smallest and most distant planet in the sun's family. Because it is so far away, Pluto remains largely mysterious. Yet in recent years astronomers have found important clues to its physical features, formation, and relationship with its single moon, Charon.

Discusses the orbit, atmosphere, and exploration of the dwarf planet Pluto.

A lively and informative look at the dwarf planet Pluto, from its discovery to the recent controversy over its status as a planet. The book describes Pluto's place in the solar system, its moons, its orbit, what we know of its physical features, and the difficulties scientists encounter in studying this mysterious body.

Pluto is too big to be an asteroid and too small to be a planet, so scientists call it a dwarf planet. It’s so far away from the sun that it gets no warmth at all, so it’s covered in a thick layer of ice. Readers learn fun facts such as these as they explore the world of our solar system’s dwarf planets. Informative diagrams, full-color photographs, and accessible text help readers discover more about Pluto and the other dwarf planets in our solar system.

Pluto, once considered the ninth planet in our solar system, is now classified as one of the largest dwarf planets in the Kuiper Belt. But what is a dwarf planet? And what is the Kuiper Belt? This engaging book answers these questions while exploring the unique features of Pluto, its moon Charon, and other major dwarf planets like Eris and Ceres.

In Dwarf Planets: Pluto and the Lesser Planets, students will learn about the five discovered dwarf planets in our solar system and make observations about orbital patterns, new discoveries, and more. Filled with fun facts, young learners will love exploring the scientific information and drawing conclusions about life now and in the future. The Inside Outer Space series takes readers on an intergalactic journey that unravels the mysteries of the universe. Each 24-page book informs readers in grades K–3 on the Sun, Earth, planets, and stars, while also igniting imaginations about the unknown. Stunning photographs and diagrams engage readers, while text-based questions aid in reading comprehension
