Chelyabinsk Meteorite as a Proxy for Studying the Properties of Potentially Hazardous Asteroids and Impact Deflection Strategies

摘要: Most asteroids of the near-Earth population have experienced significant collisional processing since they formed, being disrupted and excavated consequently producing smaller bodies that are delivered from Main asteroid Belt to region, thanks planetary resonances non-gravitational forces. By studying meteorites arrived Earth we can obtain clues on this through study shock metamorphism brecciation their rock constituents, among other features. The massive Chelyabinsk meteorite fall produced about one metric ton be analyzed decipher physical processes affecting surface Potentially Hazardous Asteroid. Here describe properties samples, how impact has affected albedos, a first step in order relate data with reflectance population. This information will major interest for future deflecting missions.
