Small bodies in the solar system, like comets, asteroids and Transneptunian objects (TNOs), are remnants from the time of the formation of our solar system 4.6 billion years ago. Their study gives clues about the formation scenario, and the physical conditions and compositional environment in the early time, and helps to understand how the solar system evolved to its present state. We observe these objects with Earth-based telescopes and with remote and in situ sensing instruments from space to determine their physical properties and chemical composition. We participate in dedicated spacecraft missions visiting comets and asteroids to study their properties from a close distance and by taking gas, dust and surface samples.
