Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
Venus's orbital dust ring is suspected to originate either from yet undetected Venus trailing asteroids, [13] interplanetary dust migrating in waves from orbital space to orbital space, or from the remains of the Solar System's circumstellar disc, out of which its proto-planetary disc and then itself, the Solar planetary system, formed.

Dust astronomy is a subfield of astronomy that uses the information contained in individual cosmic dust particles ranging from their dynamical state to its isotopic, elemental, molecular, and mineralogical composition in order to obtain information on the astronomical objects occurring in outer space. Dust astronomy overlaps with the fields of ...
This month’s dust cloud is more resilient than usual—its dust is so opaque and thick that it can be clearly seen from the International Space Station, while its predecessors have been ghostly ...
Cosmic dust is widely present in outer space, where gas and dust clouds are the primary precursors for planetary systems. The zodiacal light, as seen in a dark night sky, is produced by sunlight reflected from particles of dust in orbit around the Sun. The tails of comets are produced by emissions of dust and ionized gas from the body of the comet.
A meteoroid (/ ˈ m iː t i ə r ɔɪ d / MEE-tee-ə-royd) [1] is a small rocky or metallic body in outer space. Meteoroids are distinguished as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. [2] Objects smaller than meteoroids are classified as micrometeoroids or space dust.
Space dust that is fired from the Moon could protect humanity from the effects of global warming, scientists have said. Dust could be fired from the lunar surface into the middle ground between us ...
