Asteroid classification is the study of categorizing asteroids based on their physical and chemical properties. This involves analyzing the composition, size, shape, rotation rate, and surface features of asteroids to determine their origin and evolutionary history. Asteroids are typically classified into groups such as C-type (carbon-rich), S-type (silicate-rich), and M-type (metal-rich) based on their spectra and reflectance properties. This classification system helps astronomers better understand the diversity of asteroids in our solar system and can provide valuable insights into their formation and evolution.
