A chondrite /ˈkɒndraɪt/ is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids. Some such bodies that are captured in the planet's gravity well become the most common type of meteorite by (whether quickly, o… WebJan 1, 2024 · In addition, the chondrite is assigned a petrologic type, which is an indication of the type of asteroidal processing it has experienced.
