The first known description of tektites comes from China around 900 B.C., during the T'ang dynasty, in a book by Liu Sun, Ling Piao Lu Yi, loosely translated as "Notes on the Wonders Beyond the Nanling Mountains in Kwangtung". (6, 7), Are meteorites heavy? This exterior is formed as friction from the atmosphere melts the meteorite as it crashes toward Earth. There are three main groups of meteorite. Explain that sometimes meteorites do not completely burn up in the atmosphere, and can 'land' on Earth. The oldest particles in a meteorite, calcium-aluminum-rich inclusions from carbonaceous chondrites, have been dated at 4.56 billion years old. When the surface of the meteorite begins to melt during entry into the atmosphere, some areas of the meteorites are eroded by the melting more than others, almost like someone is taking little scoops of material out. The most basic types, known as carbonaceous chondrites, are rich in water, sulphur and organic material. The CI group, for instance, is named after the Ivuna meteorite, which crashed into Tanzania in 1938. The new system improves NASA's capabilities to assess the impact risk of asteroids that can come close to our planet. Ordinary chondrites can be classified into three main groups. 62,559 Meteorite Images, Stock Photos & Vectors | Shutterstock Like ordinary chondrites, carbonaceous chondrites can be more minutely classified based on their mineral composition.

Carbonaceous chondrites are often named after the first specimen of that type recovered. Much of meteorite classification is based, in fact, on how much iron a They are named for the hardened droplets of lava, called chondrules, embedded in them. However, other scientists think that there are very few olivine-rich meteorites in the asteroid belt, and too many pallasite meteorites for them all to have come from a core-mantle boundary. very heavy, and have often been forged into unusual or even spectacular shapes Iron meteorites are the most massive meteorites ever discovered.
