WebThe Moon was formed with much less iron and other heavy elements to form its core. Lunar rock samples and meteorites contain the chemistry of the Moon and support the Giant Impact hypothesis. The searing heat of the impact drove away most of the gases and liquids, leaving a relatively dry world. WebThe ejecta pattern around most fresh Martian impact craters is distinctively different from that around lunar and mercurian craters. On the Moon and on Mercury, the ejecta typically have a coarse, disordered texture close to the rim. Farther out, the texture becomes finer and, with increasing radial distance, grades imperceptibly into dense ...
