Cosmic dust
Cosmic dust can be taken to be all dust in the cosmos, as its name implies, or limited to space dust in our solar system, as scientists who study dust in the solar system prefer. 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.The above text is a snippet from Wikipedia: Cosmic dust
