taken to be all dust in the cosmos, as its name implies, or
limited to space dust in the Solar System. It is for the most
part a type of small dust particles which are a few molecules to
0.1 µm in size. A smaller fraction of all dust in space consists
of larger refractory minerals that condensed as matter left the
stars. It is called "stardust" and is included in a separate
section below.  Cosmic dust can be further distinguished by its
astronomical location: intergalactic dust, interstellar dust,
interplanetary dust (such as in the zodiacal cloud) and
circumplanetary dust (such as in a planetary ring). In the Solar
System, interplanetary dust causes the zodiacal light. Sources
of Solar System dust include comet dust, asteroidal dust, dust
from the Kuiper belt, and interstellar dust passing through the
Solar System. The terminol
