Partial list of possible candidates for meteorite parent bodies

Most, if not all, meteorites are believed to come from bodies in orbit around the sun which have collided. Fragments of these collisions are drawn towards the Earth under the influence of gravity, finally ending their journey on a blazing trail through the atmosphere before hitting the surface.

There is much speculation about what these parent bodies might be. In some cases (such as the Martian and Lunar meteorites) we have direct samples to compare with – physically, from the Apollo missions in the case of the moon rocks, and remotely via the many Mars landers which have sampled the material on the Red Planet.

More indirect means can be used: for instance, crushing fresh meteoritic material and comparing its spectral response against the spectra of some of the asteroids.

Below is a list of the major classes of meteorites, and indications of suspected or known parent bodies. Note that this list cannot be regarded as definitive!
