Our solar system has a ring of dust that produces an observable phenomenon called the Zodiacal Light. This dust was created by collisions among asteroids and is spread across a broad belt. Dusty disks have been discovered around other stars that have similarities to what we see in our solar system. The study of these disks can inform us about the presence of asteroid belts or Kuiper Belts around other stars. They may also provide insight into the formation of planets like Earth.
