Meteorites and asteroides. Classification, geology and exploration / Метеориты и астероиды. Классификация, геология и изучение

In this book, the authors present current research in the study of the classification, geology and exploration of asteroids and meteorites. Topics discussed include meteorites and their asteroidal parent bodies; the diversion and exploitation of ice-rich NEOs using the solar collector; radar characteristics of asteroid 33342 (1998 WT24); asteroid dimensions and the truncated pareto distribution; Hilda asteroids in the Jupiter neighborhood; and asteroid Apophis and 1950 DA.

Chapter 1 - Meteorites are fragments of planetary objects, most often of asteroids, that have broken off of their parent bodies and made their way to Earth. For years, one of the primary goals of planetary scientists who study these objects has been to determine possible connections between recovered meteorites and their potential parent bodies in the asteroid belt and near-Earth asteroid population. Mineralogies and chemistries of meteorites are determined in laboratories, using traditional analytical techniques such as Xray diffraction and electron microprobe phase analysis. This, along with oxygen isotopic analysis, has resulted in the identification of approximately twenty-five different groups of stony and stony-iron meteorites (those that contain silicate mineral and Fe-Ni metal) and thirteen groups of iron meteorites. Iron and stony-iron meteorites are derived from differentiated asteroids, or those that have a core, mantle, and a crust. Each meteorite group is usually thought to be derived from a different parent body. <...>
