Dwarf Planets

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.

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 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.

Dwarf planets (which were formerly called asteroids except for the planet Pluto), and the smaller Solar System bodies still called asteroids today, are making front page news, particularly those that are newly discovered and those that might present a hazard to life on Earth by impacting our planet. In this age of giant telescopes and space probes, these small Solar System bodies have advanced from being tiny points of light to bodies worthy of widespread study. This book describes the dwarf planets and asteroids themselves, their origins, orbits, and composition, and at how amateur astronomers can play a part in their detection, tracking, and imaging. The book is divided into two parts. Part I describes physical properties (including taxonomic types) of dwarf planets and asteroids, how they formed in the early life of the Solar System, and how they evolved to their present positions, groups, and families. It also covers the properties used to define these small Solar System bodies: magnitude, rotation rates (described by their light-curves), and orbital characteristics. Part II opens with a description of the hardware and software an amateur or practical astronomer needs to observe and also to image asteroids. Then numerous observing techniques are covered in depth. Finally, there are lists of relevant amateur and professional organizations and how to submit your own observations to them.

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

Did you know that there are five known dwarf planets? They are called Ceres, Pluto, Haumea, Makemake, and Eris. Find out more in Dwarf Planets, a Planets book. This is an AV2 media enhanced book. A unique book code printed on page 2 unlocks multimedia content. This book comes alive with embedded weblinks, audio and video clips, activities, and other features, such as a slide show, matching word activity, and quiz.

A basic introduction to dwarf planets, such as Pluto, their sizes, compositions, and places within our solar system.

Our solar system used to have nine planets. But recently, scientists ruled that Pluto was actually a "dwarf planet." So what exactly is a dwarf planet, how many of them are there, and how do scientists study and classify them? All the facts you need, and lots more, are included in this up-to-date book, featuring a center spread with fast facts.

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.
