One group of these objects is named after Heinrich Kreutz. A transparent, silicon-based solid known as aerogel is used to collect samples of these objects. They can be divided into Type I and Type II depending on the nature of their (*) coma. These objects are divided into short-period, which come from the Kuiper Belt, and long-period, which come from the Oort Cloud.
