Cosmic dust can also be called Interplanetary matter is a dust made up of several molecules and atoms, for example: 0.1 mm molecules. It exists between any two bodies in space. What we see as black in space is not a vacuum, it is just cosmic dust but divided into billions of pieces, so it is not seen. It can only be seen under a microscope. Cosmic dust is formed from the disintegration of celestial bodies, such as comets, planets, dwarf planets, asteroids, etc. and from the remnants of the original matter from the formation of the Solar System. The cosmic dust can also be observed by anti-sunlight, when the Sun sets, thus seeing the gaseous tail of the Earth. And through the zodiacal light, which is in the form of a cone in the plane of the ecliptic, after the sun has set.
