Chondrites are a type of stony meteorite that are the most common type of meteorite found on Earth. They are composed primarily of silicate minerals and metallic iron-nickel. Chondrites are thought to be some of the oldest and most primitive materials in the Solar System, dating back over 4.5 billion years. They are important in understanding the early formation and evolution of the Solar System, as they have remained relatively unaltered since their formation. Chondrites are classified into different groups based on their mineralogical and chemical compositions, and studying them can provide valuable insights into the processes that occurred in the early stages of our Solar System's history.
