What is another word for micrometeor?
Pronunciation: [mˈa͡ɪkɹə͡ʊmˌiːtɪə] (IPA) 
Micrometeor, also known as a micrometeoroid, refers to a tiny particle of matter, usually smaller than a grain of sand or rice, that enters the Earth's atmosphere from outer space. Other synonyms for micrometeor include space dust, meteorite dust, cosmic debris, and interplanetary dust particle. These particles are often too small to cause significant damage to spacecraft or to humans, but can still create bright meteor trails when they burn up in the atmosphere. The study of these particles can also provide valuable insights into the origin and evolution of our solar system. There are ongoing efforts to collect micrometeoroid particles from space for further analysis and research.
