Interplanetary dust cloud

The interplanetary dust cloud is made up of cosmic dust or small particles floating in outer space. It is in the space between planets within planetary systems, such as the Solar System.

This system of particles has been studied for many years in order to understand it and its relationship to larger bodies. There are several methods to obtain space dust measurement. 

The total mass of the interplanetary dust cloud is approximately , or the mass of an asteroid of radius 15 km (with density of about 2.5 g/cm3).
