The interplanetary dust cloud illuminated and visible as zodiacal light, in this composite image of the night sky above the northern and southern hemisphere.

The interplanetary dust cloud is made up of cosmic dust or small particles floating in outer space.[1] 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 3.5×1016 kg, or the mass of an asteroid of radius 15 km (with density of about 2.5 g/cm3).[2]
