Meteorite classification may indicate that a "genetic" relationship exists between similar meteorite specimens. Similarly classified meteorites may share a common origin, and therefore may come from the same astronomical object (such as a planet, asteroid, or moon) known as a parent body. However, with current scientific knowledge, these types ...
A small number of meteorite falls have been observed with automated cameras and recovered following calculation of the impact point. The first of these was the Příbram meteorite, which fell in Czechoslovakia (now the Czech Republic) in 1959. [48] In this case, two cameras used to photograph meteors captured images of the fireball.
Stony-iron meteorites or siderolites are meteorites that consist of nearly equal parts of meteoric iron and silicates. This distinguishes them from the stony meteorites, that are mostly silicates, and the iron meteorites, that are mostly meteoric iron. [1] Stony-iron meteorites are all differentiated, meaning that they show signs of alteration.
Fossil meteorite – a meteorite that was buried under layers of sediment before the start of the Quaternary period. Some or all of the original cosmic material has been replaced by diagenetic minerals. [3]: 320 (It is, however, not a fossil). Fusion crust – a coating on meteorites that forms during their passage through the atmosphere.
A chondrite / ˈ k ɒ n d r aɪ t / is a stony (non-metallic) meteorite that has not been modified by either melting or differentiation of the parent body. [a] [1] They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids.
The Sikhote-Alin meteorite is the heaviest of these and was an observed fall, [7] while the Old Woman meteorite is, at 38 × 34 × 30 inches (970 × 860 × 760 mm) and 6,070 pounds (2,750 kg) originally, the largest meteorite found in California and the second largest found in the United States.
It is a metallic meteorite, consisting basically of iron, with the following elements: 6.6% Ni, 0.47% Co, 0.22% P, and traces of S and C in much smaller quantities, only measured in parts per million. [7] The meteorite has characteristic Widmanstätten pattern iron/nickel crystals as will as inclusions containing phosphorus and sulfur. [1]]
Howardites are achondritic stony meteorites that originate from the surface of the asteroid 4 Vesta, and as such are part of the HED meteorite clan. [ 1 ] [ 2 ] There are about 200 distinct members known.
