Small bodies refer to objects in our solar system that are smaller than planets, such as asteroids, comets, and meteoroids. These objects are typically composed of rock, metal, or ice, and can vary in size from just a few meters to hundreds of kilometers in diameter. Studying small bodies is important for understanding the formation and evolution of the solar system, as well as for assessing potential threats to Earth from asteroid impacts. Researchers study small bodies using a variety of techniques, including telescopic observations, spacecraft missions, and laboratory analysis of meteorite samples.
