Meteorites are not a specific type of rock, but rather fragments of asteroids, comets, or other celestial bodies that have fallen to Earth. They can be made of various materials, including:

* Iron meteorites: Mostly composed of iron and nickel, with some other trace elements.

* Stony meteorites: Primarily composed of silicate minerals like olivine and pyroxene.

* Stony-iron meteorites: A mixture of iron-nickel and silicate minerals.

So, a meteorite can be classified as a stone, iron, or stony-iron depending on its composition.
