Most asteroids come from a “belt” that orbits the sun between the orbits of Mars and Jupiter. Comets are born in the frozen reaches beyond Neptune. Both are remnants leftover from the birth of our solar system billions of years ago. Readers will be amazed to learn all about these fascinating space rocks. The scientific text is paired with stunning photographs and illustrations of cosmic forces at work. A detailed graphic organizer provides a convenient study guide for comparing and contrasting comets and asteroids.

It’s the plot of many sci-fi movies: An asteroid is hurtling toward Earth! But is this really a danger we face? And what exactly are asteroids? This book answers these and many more questions about the millions of asteroids in our solar system and the large orbiting belt in which most are found.

An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today’s efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

Can you tell asteroids, meteors and comets apart? Focus on their characteristics and you should! This book will give you information on the identifying characteristics of asteroids, meteors and comets. At the end of this book, you should be able to differentiate these heavenly bodies based on pictures and even when you see them in a telescope! Grab a copy today.

Discusses the spinning of the Earth, the progress of day into night, and the reasons for the spectacular colors and shadows that accompany sunrise and sunset.

Explores how comets, meteors, and asteroids move through our solar system, and explains the ingredients that make a comet's tail and other topics
