Cosmic dust
hideCosmic 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 (potentially concentrated in a nebula), interplanetary dust (such as in a circumstellar disk) and circumplanetary dust (such as in a planetary ring).
In our own Solar System, interplanetary dust causes the zodiacal light. Sources include comet dust, asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through our solar system.
