Cosmic dust is a type of
dust composed of particles in space which are a few
molecules to 0.1 mm in size. Cosmic dust can be further distinguished by its astronomical location; for example: intergalactic dust, interstellar dust, circumplanetary dust, dust clouds around other stars, and the major interplanetary dust components to our own
zodiacal dust complex (seen in visible light as the
zodiacal light):
Comet dust, asteroidal dust plus some of the less significant contributors:
Kuiper belt dust, interstellar dust passing through our solar system, and beta meteoroids.
