Also known as planetoid, asteroids

An asteroid is a minor planet—an object larger than a meteoroid (thus 1 meter or larger) that is neither a planet nor an identified comet—that orbits within the inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type (carbonaceous), M-type (metallic), or S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an

AI overview

An asteroid is a rocky, metallic, or icy object at least 1 meter in size that orbits the Sun in the inner Solar System, distinct from planets and comets. Asteroids vary widely in size and composition, ranging from small rubble piles to bodies nearly 1,000 kilometers across, and they matter because understanding their characteristics and movements helps us track potential impacts and learn about the early Solar System.
