The new system improves NASA's capabilities to assess the impact risk of asteroids that can come close to our planet. The rocky planets Mercury, Venus, Earth and Mars were formed in this way, giving them planetary crusts, mantles and cores. The extinction of most life on Earth 65 million years ago is a good example of that. Carbonaceous chondrites can also be named after the place where the first specimen of the type was found. Meteorites are fragments of rock or iron from a meteoroid, asteroid, or possibly a comet that pass through a planet or moon's atmosphere and survive the impact on the surface (1). a number of structural classes.
