Where do meteorites come from?

The origin of rocks from space with Parent Body Pairings!

There is a theory that certain classes of meteorites originate from a particular 'parent body' in our solar system. During significant disruption to the parent body, pieces can be broken off such as when two asteroids collide. Some of these pieces then make it to Earth. While the Martian and Lunar meteorites are virtually un-arguably from Mars and the Moon, it is only really educated speculation about the other classes. Because we have been to the Moon and Mars, it is possible to classify meteorites using the data collected from those missions. With the other classifications, we need to use methods like spectral analysis to determine their origin. Listed below are some meteorite classifications and the name of the parent body they are thought to originate from.
