Asteroids Meteorites And Comets

Praise for the previous edition:" ... offer[s] detail-rich discussions ..."

Whether they appear as distant specks in an astronomer's telescope or shoot brilliantly across the evening sky, comets, meteors, and asteroids have fascinated sky gazers throughout history. But where do these racing celestial bodies come from, and what can they teach us about our universe? Join Seymour Simon for a look at the fiery mystery and wild wonder of these luminous bodies of night.

This fascinating text is a perfect companion for any student interested in a more authoritative source on the subject of asteroids, meteors, meteorites, and comets. Readers will learn, following the Next Generation Science Standards in the area of the Earth and the solar system, the scientific differences between these four celestial objects. They'll also study their features, compositions, characteristics, classifications, and history of their observation. This book is perfect for the student doing a report on the subject or one who is curious about the space sciences and would like detailed information instead of a general overview.

When many young readers think of space, they just think of the planets, and perhaps the sun and moon. But there's much more to space than just those things. Asteroids, meteors, and comets are just a few of the other things that exist in what we know as space. Readers of this delightful book will learn all about these amazing, often rocky or icy, objects. Fact boxes emphasizing key numbers are included throughout the book, while colorful photographs and diagrams also help visual learners understand many of these figures.

"Asteroids, comets, and other space rocks rush around the solar system. Learn about these fascinating flying masses and their place in the solar system."

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

From earliest times, humans have wondered about the sky above them and have studied all visible objects. People began to identify differences between stars and planets, and as technology advanced with telescopes and space probes, they sought deeper understanding of the millions of bits of debris rocketing through the solar system. Scientists determined that most of these objects are left over from the creation of the planets and their moons. They classified these leftovers into categories such as asteroids, comets, and meteors. In this book, we'll explore seven wonders of asteroids, comets, and meteors. Ceres is a huge mountain-sized asteroid that orbits with other asteroids between Mars and Jupiter. Other marvels include Ganymede, the largest asteroid in the group called Earthgrazers or Near-Earth Objects, and Halley's comet, a ball of ice, that passes Earth every seventy-five or so years. We'll also explore the amazing impact that space debris can have on planets and moons. The Borealis Basin, a wondrous crater more than 5,000 miles across, formed when an asteroid collided with Mars in the ancient past. Then we will travel to the far-off Kuiper belt, where as many as 200 million icy bodies orbit, and wonder at the mystery of planetlike objects, such as Pluto and Charon. Finally, we’ll can experience a space wonder firsthand by standing outside on a night in August to watch the spectacular Perseid meteor shower fill the sky.
