Explanation:

A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.

More than 95% of meteorites observed to fall to Earth are stony. They can be divided into chondrites and achondrites. Both types are composed mostly of silicate minerals, but the great majority also contain metallic iron in small-scattered grains. Pyroxenes are common in meteorites and in extrusive igneous rocks, especially basalt. Pyroxenes are the most significant and abundant group of rock-forming ferromagnesium silicates.
