We may not be able to see asteroids without a telescope, but there are thousands of these space rocks circling the sun. Readers learn about asteroid formation, size, shape, and orbits. They are also introduced to the methods that scientists use to track asteroids. Fast facts and a hands-on activity expand the reader’s learning experience, while full-color images enrich the narrative with additional details and examples. This book supports English Language Arts standards and also correlates directly with Next Generation Science Standards.
