Explores how comets, meteors, and asteroids move through our solar system, and explains the ingredients that make a comet's tail and other topics
"Asteroids, comets, and other space rocks rush around the solar system. Learn about these fascinating flying masses and their place in the solar system."
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.
Describes the role that collisions with meteors, comets, and asteroids have played in the history of Earth and other planets in the solar system and examines what is being done to protect Earth from future collisions.
Primitive Meteorites and Asteroids: Physical, Chemical, and Spectroscopic Observations Paving the Way to Exploration covers the physical, chemical and spectroscopic aspects of asteroids, providing important data and research on carbonaceous chondrites and primitive meteorites. This information is crucial to the success of missions to parent bodies, thus contributing to an understanding of the early solar system. The book offers an interdisciplinary perspective relevant to many fields of planetary science, as well as cosmochemistry, planetary astronomy, astrobiology, geology and space engineering. Including contributions from planetary and missions scientists worldwide, the book collects the fundamental knowledge and cutting-edge research on carbonaceous chondrites and their parent bodies into one accessible resource, thus contributing to the future of space exploration. - Presents the most current data and information on the mission-relevant characteristics of primitive asteroids - Addresses the physical, chemical and spectral characteristics of carbonaceous chondritic meteorites and the bearings on successful exploration of their parent asteroids - Includes chapters on geotechnical properties and resource extraction
An accessible and interesting presentation of the diverse range of historical material about comets.
'Astonishing' - New Scientist Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants. Exploring comets and asteroids also allows us to shape the story of Earth's future, enabling us to protect our precious planet from the threat of a catastrophic impact from space, and maybe to even recover valuable raw materials from them. This cosmic bounty could be as useful in space as it is on Earth, providing the necessary fuel and supplies for humans as they voyage into deep space to explore more distant locations within the Solar System. Catching Stardust tells the story of these enigmatic celestial objects, revealing how scientists are using them to help understand a crucial time in our history – the birth of the Solar System, and everything contained within it.
What is unique about Richard Norton's book is that it is both a field guide to observing meteors, and also a field guide to locating, preparing and analysing meteorites. In addition to giving the reader information about observing techniques for meteors, this book also provides a fully detailed account of the types of meteorites, how and where to find them, how to prepare and analyse them. The book provides everything the amateur astronomer (or geologist!) needs to know about meteors and meteorites. It is thus the only complete book on the subject available at present.
Leading specialists in various disciplines were first invited to a multidisciplinary workshop funded by ICSU on the topic to gain a better appreciation and perspective on the subject of comet/asteroid impacts as viewed by different disciplines. This volume provides a necessary link between various disciplines and comet/asteroid impacts.
Meteorites - as well as shooting stars and meteors - result from a collision of a solid body from space with our Earth, but only meteorites are able to penetrate the Earth's protective shield, the atmosphere, and fall to the Earth's surface. Apart from lunar samples, they are the only materials from beyond the Earth which we can probe and study. This book gives a concise and up-to-date description of meteorites - fall phenomena, chemical and mineral composition, classification - as well as a discussion of their formation and origin, which also tells us the story of the formation of our planetary system. The text is understandable for laymen and students, but can also be used as an introduction to the field for students and scientists.
