Meteoritics25, 323-327. In the early universe, when the Solar System had yet to be cleared of the debris out of which it formed, which type of object would have been most likely to deposit water onto Earth's surface? Perhaps the most prominent of these are chondrules. The explosion released the energy equivalent of around 440,000 tons of TNT and generated a shock wave that blew out windows over 200 square miles (518 square kilometers) and damaged buildings. From NASA Goddard. And they can study how old the meteorites are up to 4.6 billion years. Mittlefehldt D. W., McCoy T. J., Goodrich C. A., and Kracher A. There is little or no Fe(III) in freshly fallen meteorites, however; it is all Fe(II), ferrous iron, and Fe(zero), iron metal. Some meteorites (carbonaceous chondrites) date back to the origin of the Solar System at around 4.56 Ga ago, and were a major contributor to the bulk composition of the rocky planets.

The Perseids are already showing up in our night skies, and they peak in mid-August. Lunar meteorites are achondrites that crashed to Earth from the Moon, while Martian achondrites crashed to Earth from our neighbor planet, Mars. Meteorites with isotopic signatures and mineral contents so different from others and from terrestrial igneous rocks are deemed to have a Martian origin by a process of elimination. Very few meteorites, only about 0.2 percent, come from Mars and the Moon. Scientists are able to tell the rocks came from Mars and the Moon because their composition matches chemical analysis of rocks conducted during NASAs robotic explorations of Mars and the moon rocks recovered during the Apollo lunar missions.
