A carbonaceous chondrite is a type of meteorite that contains a high percentage of carbon and other organic compounds. These meteorites are believed to be some of the oldest materials in the solar system, dating back over 4.5 billion years. They provide valuable insights into the early solar system and the building blocks of planets. These meteorites are rich in minerals, including clay and sulfides, and often contain small amounts of water. Carbonaceous chondrites are classified into different groups based on their chemical composition, with notable examples including CI, CM, and CO chondrites. Their study helps scientists understand the origins of organic molecules and the potential for life beyond Earth.
