A meteorite is a solid object found on Earth's surface after it enters earth's atmosphere from interplanetary space. Meteorites are either observed "falls", or were found some time after they fell, i.e., "finds". Meteorites are classified into different types based on their mineral composition, textures, the presence or absence of chondrules, and other criteria. Chondritic meteorites, or "chondrites" are from parent bodies (asteroids) that never formed metal-rich cores. They contain many rock-forming elements in the same ratios as observed in the Sun's photosphere. "Achondrites" include irons (many from ancient planetary cores), rocks from the Moon, Mars, and Vesta, and meteorites that are not chondrites.
