Chondrite – stony meteorites unmodified by melting or differentiation of the parent body
Chondrule – millimetre-scale round grains found in chondrites
Clan – meteorites that are not similar enough to form a group, but are also not too different from each other to be put in separate classes.
Class – two or more groups that have a similar chemistry and oxygen isotope ratios.
Compositional type – a classification based on overall composition, for example stony, iron, stony-iron (as introduced by Maskelyne). Can also refer to the composition deduced from spectroscopy of asteroids.
Fall – a meteorite that was seen while it fell to Earth and found.
Find – a meteorite that was found without seeing it fall.
Fossil meteorite – a meteorite that was buried under layers of sediment before the start of the Quaternaryperiod. Some or all of the original cosmic material has been replaced by diagenetic minerals.: 320 (It is, however, not a fossil).
Fusion crust – a coating on meteorites that forms during their passage through the atmosphere.
Group – a collection of five or more meteorites sharing similar characteristics.
Grouplet – a collection of fewer than five meteorites sharing similar characteristics.
Hammer Stone – a specific individual meteorite that has hit either a human, man-made object, and/or an animal.
Panspermia – the hypothesis that life could reach other planets by the means of meteorites and/or comets.
Parent body – the celestial body from which originates a meteorite or a class of meteorites.
Petrologic type – a classification scheme that expresses the degree to which a meteorite has been affected by the secondary processes of thermal metamorphism and aqueous alteration on the parent asteroid.
Superbolide – is a bolide that reaches an apparent magnitude of −17 or brighter, which is roughly 100 times brighter than the full moon. Recent examples of superbolides include the Sutter's Mill meteorite and the Chelyabinsk meteor.
