Asteroids
Where do asteroids come from and what are they made of? What clues do they hold about the evolution of the Solar System? Scientists have catalogued hundreds of thousands of asteroids, and many are thought to contain water and amino acids, the building blocks of life. Michael K. Shepard tells the fascinating story of their discovery, and what they can tell us about the history of our own planet. He describes how we find and study asteroids, what they look like through the eyes of powerful telescopes and spacecraft, and plans for future sample return missions. This timely book interweaves accessible scientific explanations with historical background and personal narrative, providing an engaging read for anyone curious about asteroids and what they may mean for our future - both as threats and opportunities.
Asteroids II
"Asteroids II will have some bearing on meteorite research, and will help to clarify our understanding of the many specimens held in both private and public collections throughout the world. I commend the book without reservation."--J.P. Lavielle Impact "This monograph will become indispensable for everybody engaged in the rapidly expanding asteroid research or interested in its current state."--Space Science Reviews "This is an excellent introduction to the subject, recommended for schools with astronomy programs."--Academic Library Review
20 Fun Facts About Asteroids and Comets
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.
Asteroids, Meteors, and Comets
With its age-appropriate text, helpful charts, colorful design, and vivid illustrations and photography, this series is perfect for students working on reports and projects or for the budding astronomer fascinated by what exists beyond our planet.
Asteroids and the Asteroid Belt
Describes how asteroids are formed and discusses the types of asteroids that are contained in the asteroid belt between the orbits of Mars and Jupiter, with details about some of the asteroid collisions from the past.
Asteroids
A unique, wide-ranging examination of asteroid exploration and our future in space Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is asteroid exploration, for the strong motives of love, fear, and greed. Elvis’s personal motivation is one of scientific love—asteroid investigations may teach us about the composition of the solar system and the origins of life. A more compelling reason may be fear—of a dinosaur killer–sized asteroid hitting our planet. Finally, Elvis maintains, we should consider greed: asteroids likely hold vast riches, such as large platinum deposits, and mining them could provide both a new industry and a funding source for bolder space exploration. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to “space billiards,” and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.
Asteroids, Meteorites, and Comets
Discusses the solar system bodies that are not one of the nine planets or their moons. This volume describes the discoveries of various asteroids, along with the long centuries of argument over the nature of meteorites and impact craters. It is useful for those interested in understanding the science and history of these bodies.
Asteroids, Comets, and Meteorites
Looks at asteroids, comets and meteorites, including what they are, how they are formed, how they have affected the history of Earth, and definitions of related terms.
Asteroids
With the bulk of asteroids floating in space between the orbits of Mars and Jupiter, astronomers puzzle over where these rocks came from. Are they the remnants of a planet? Excess not used in the formation of the Solar System? Nothing more than random bits of debris? The location of the belt makes for a quasi-barrier separating the inner from the outer planets. Perhaps asteroids were meant to discourage human space exploration. NASA has sent missions to explore the asteroid belt and the rocks themselves, and those missions have yielded some interesting observations on the composition of the asteroids but no definitive answer as to their origin. Earth-based tools such as telescopes and satell...
