Achondrites lack chondrules, originate on differentiated planetary bodies (ie planetary bodies with a distinct core and crust), such as asteroids, planets, or moons, and were reformed from molten fragments that were flung into space as the result of another collision.
Because achondrites closely resemble terrestrial rocks to the naked eye, they are less commmonly encountered as finds.
The achondrites include angrites, aubrites, diogenites, eucrites, howardites, lunar meteorites, martian meteorites, primitive achondrites (such as acapulcoites, brachinites, lodranites, and winonaites), and ureilites.
