What are rocky metallic objects that orbit the sun but are to small to be considered planets?

Rocky metallic objects that orbit the Sun but are too small to be considered planets are known as asteroids. These celestial bodies primarily reside in the asteroid belt between Mars and Jupiter, although they can be found throughout the solar system. Asteroids vary in size and composition, with some containing significant amounts of metal, while others are more like rocky debris. They are remnants from the early solar system, providing valuable insights into its formation and evolution.
