Land since they disintegrate when entering the atmosphere. In general, celestial bodies do not arrive as meteorites to Earth. They are the rarest, accounting for 1.8 percent of those that fall on Earth. They differ from the previous ones because they have metals and silicate rocks in equal proportion. Lastly are the stony-metallic meteoriteswhich are also called lithosiderites, mixed meteorites either sideroliths. Note that, on the other hand, metallics only represent 5.7 percent of those that fall on Earth. ![]() Metallic meteorites are very large and dense: among all those that have been collected, the weight is greater than 500 tons, nearly 90 percent of the total mass of known meteorites. It is estimated that these meteorites come from the cores of asteroids that were destroyed after an impact. In general, with their compounds they form alloys which are called taenite Y kamacita. With respect to metallic meteoritesother names they receive are holosiderites, siderites, ferrous meteorites Y iron meteorites. The study of chondrites is essential to understand the origin and antiquity of the solar system, the existence of water on our planet, the origin of life and the synthesis of organic compounds. The chondriteswhich can also be called chondrites, in masculine, are found in considerably larger numbers than achondrites: more than 85 percent of the meteorites that fall on Earth. We finally found the stony-metallic meteoriteswith rocky materials and metals. The metallic meteorites, on the other hand, have iron and nickel as main components. The stony meteorites either rocky They are composed mainly of silicate minerals and are divided into achondrites (which underwent fusion processes and differed from the asteroid or planet of origin) and chondrites (which did not record fusion processes or differ from the Body from which they come). One can distinguish between various classes of meteorites. But the meteorite itself is the solid element that falls from the darling. A meteor is a atmospheric phenomenon that can have different characteristics: the luminosity generated by the meteorite when it disintegrates forms part of the meteors. It is important not to confuse between meteorite and meteor. These fragments reach the surface since, when passing through the atmosphere, they do not completely disintegrate. The meteorites are remains of celestial bodies that impact on the Land or about any other star. There are no known asteroid threats to Earth). (DART’s target asteroid is NOT a threat to Earth. DART is a test.
