Editorial Reviews

Children's Literature - Susan Treadway M.Ed.
Explosions, crashes, streaks, gravitational forces, and other aerospace effects are covered with kid-friendly explanations and splendid NASA drawings, diagrams and photographs. Books in the "What's Amazing About Space?" series address exoplanets, black holes, travel, robots, and the International Space Station (ISS). Engaging chapter books convey lively action even as historical and current topics are presented. Orbiting space debris, meteors, enormous rocks, comets, and broken or inoperable equipment primarily burn up before damaging the Earth. If possible, a missile is launched to break up pending dangers. If not, huge craters show the impact on Earth and other planets due to their stronger gravitational pull. For instance, an asteroid exploded in the air near Siberia, Russia about one hundred years ago. It is estimated to have weighed 220 million pounds and been as long as a tennis court. In spite of limited data, evidence was not difficult to find. Eighty million trees fell and multiple reindeer herds died, yet no one was injured or killed. Two space stations, America's Skylab (1979) and Russia's Mir (2001), became space junk when they were no longer needed; they broke up while entering Earth's atmosphere and fell into the Indian and Pacific Oceans, respectively. Skylab pieces also hit part of Australia. With the additional topics in this series, young readers will have a good start when examining similar mysteries about dangerous objects in space. Consistent formatting in these Searchlight Books includes vivid NASA photographs, diagrams and drawings with descriptive text boxes, a basic glossary, an index and a list of a few additional resources and websites. Explanations are appropriate for the age level. Reviewer: Susan Treadway, M.Ed.

Meet the Author

Buffy Silverman is the author of many books about nature and science for children. She also enjoys writing poetry for children. Buffy is lucky to live in a rural area of Michigan where inspiration is just outside the window. The sun shimmers on Stony Lake. A great blue heron flies low over the swamp. Black squirrels scamper across oak branches, stuffing leaves in their mouths and bringing them to a hollow. The animals that share her yard inspire stories and poems. With every book and article she writes, she learns more about the world.

    This is an interesting book on an assortment of objects in space that could endanger the Earth ...

    If you've ever glanced up into the sky on a clear summer's day you might see something streaking across the sky. Many people might call the object a shooting star, but "it is not really a star ... it is a small rock from outer space." When the rock comes into the Earth's atmosphere it burns and creates the light you see in the sky. Space rocks can be found circling, or orbiting the sun. They vary in size from dust sized to the largest one that "is about the size of Texas." Asteroids and comets also orbit the sun, but they tend to be much larger than space rocks. Scientists think asteroids were created when the planets formed. Comets are made of ice, dust particles, and rocks.

    Meteoroids are yet another object that orbits the sun. These also vary in size "as small as a sand grain" up to the size of a boulder. You'll learn the unusual way they form and what happens when they enter Earth's atmosphere as meteors. If any of them travel through the atmosphere and reach the ground they are called meteorites. There are other unusual objects that orbit our Earth that once served a valuable purpose, but now are considered to be space junk. In this book you'll also learn about craters (Earth and Moon), asteroid and comet strikes (Earth and Jupiter), you'll learn about the asteroid that wiped out the dinosaur population, what would happen if we received another large impact from a space object, when we might expect this to occur again, how we can protect ourselves from strikes, and you'll learn many other interesting facts about the dangers the Earth faces from objects in space.

    This is an interesting book on an assortment of objects in space that could endanger the Earth. The material in this book has a lot of information on several different space objects that could potentially strike the Earth, but has more of a fascination bent than an overly alarmist one. For the curious space loving student or wannabe astronomer this book will be of high interest. The book is generously illustrated with photographs and artist's renditions of space objects. For example, one shows what an asteroid might have looked like 65 million years ago as it struck the Earth. One of the most interesting photographs is one of a man posing with a piece of space junk, the Skylab, that fell to Earth in 1979. In the back of the book is an index, a glossary and additional recommended book and website resources to explore.
