Meteorite classification may indicate that a "genetic" relationship exists between similar meteorite specimens. Similarly classified meteorites may share a common origin, and therefore may come from the same astronomical object (such as a planet, asteroid, or moon) known as a parent body.

An asteroid becomes a meteorite when it travels to Earth from a nearby orbit or the outer solar system and collides with Earth, according to the United States Geological Survey.
A meteor or shooting star [8] is the visible passage of a meteoroid, comet, or asteroid entering Earth's atmosphere. At a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake.
Meteoritics [note 1] is the science that deals with meteors, meteorites, and meteoroids. [ note 2 ] [ 2 ] [ 3 ] It is closely connected to cosmochemistry , mineralogy and geochemistry . A specialist who studies meteoritics is known as a meteoriticist .
A chondrite / ˈ k ɒ n d r aɪ t / is a stony (non-metallic) meteorite that has not been modified by either melting or differentiation of the parent body. [a] [1] They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids.
