Peering through a telescope, you are likely to encounter a host of celestial bodies—anything from another planet to a comet—speckling the night sky. Careful observation has shown that while each object follows a unique orbit or trajectory, these entities also share numerous qualities and together provide critical information about space and the universe as a whole. This engaging volume surveys the characteristics of the diverse objects that make up the solar system as well as their distinguishing features.

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

"Describes the five dwarf planets in our solar system, including the birth of the solar system and the dwarf planets' orbits around the Sun"--Provided by publisher.

Five and counting! So far, astronomers have discovered five dwarf planets in our solar system. Pluto, which was once thought of as the ninth planet, is today classified as a dwarf planet. This book looks at the dwarf planets' characteristics, size, and orbital patterns, as well as the three rules scientists follow to identify these tiny, round space objects. Every day new discoveries are being made. Who knows how many dwarf planets we will find in the future! This book will allow students to understand that patterns in the natural world can be observed, used to describe phenomena, and used as evidence.

Rave reviews for Pluto and Charon: Ice Worlds on the Ragged Edge of the Solar System The story of the quest to understand Pluto and the resulting transformation of our concept of the diminutive planet from that of solar-system misfit to king of the Kuiper Belt is told in this book by Alan Stern and Jacqueline Mitton. Stern, a Plutophile to the core, is one of the most energetic, talented, and savvy planetary astronomers in the business today. Mitton, trained as an astronomer, is an experienced writer and editor of scientific books for nonscientists. Together they have created an immensely informative book . . . Written in an engaging and informal style, Pluto and Charon takes the reader step by step from the discovery of the ninth planet in 1930 to the current understanding of Pluto and its moon, Charon.-Sky & Telescope More than a book summarizing what we know about [the] planet, [Pluto and Charon is] about how far and how fast astronomical technology has come since 1965 . . . Stern and Mitton use the narrative of Pluto research to explain in comfortable, everyday language how such work is done . . . One of the nice touches in the book is that Stern and Mitton tell us something about each astronomer.-Astronomy Pluto and Charon presents the exploration of the ninth planet-written as a vivid historical account-for anyone with an interest in science and astronomy . . . the authors describe in simple language the methods researchers use to explore the universe and the way ever-improving instrumentation helps their knowledge advance.-Physics Today

The distinction between planets and dwarf planets is explored in this fascinating volume. It discusses the most recent scientific discoveries along with the mysteries and questions they raise. Amazing illustrations make this book beautiful as well as informative.

The reclassification of Pluto in 2006 not only decreased the number of planets in our solar system by one but also introduced the new category of dwarf planet. Readers will come to understand what separates a dwarf planet from a planet—or for that matter from any of the other bodies found within the solar system. They’ll learn about Pluto itself, as well as its fellow dwarf planets, Ceres, Makemake, Haumea, and Eris. Full of recent information, this title is sure to inspire an interest in space science among young readers.
