Cosmic dust

Porous interplanetary dust particle made from chondrite

Cosmic dust is dust in space . A distinction is made depending on its place or origin

• intergalactic dust
• interstellar dust
• interplanetary dust (which can be visible on Earth as zodiacal light )
• Circumplanetary dust , for example in planetary rings .

Cosmic dust also includes the water resources in the universe in the form of finely divided water ice (see also water synthesis in space ).

The earth captures about 30,000 tons of cosmic dust each year, most of which is interplanetary dust. The total captured cosmic matter (with gases) varies between about 150,000 and 1,000,000 tons per year.
