5000 tons of dust falling on Earth every year from space

 5000 tons of dust falling on Earth every year from space, this surprising revelation after 20 years of dust

   Scientists at the University of Paris-Saquel and the National Museum of Natural History, in collaboration with the French Polar Institute, have determined through an international program conducted for nearly 20 years that comets and asteroids cause dust on our planet Earth every year.  In this way, about five thousand two hundred tons of dust come to the earth.

  This research revealed that these interplanetary dust particles pass through our atmosphere and give birth to shooting stars.  Micromerites have always been falling on our planet.  These intertidal dust particles of comets or asteroids range from a few tenths to a hundredth of a millimeter, reaching the Earth's surface through the atmosphere.

  Researchers carried out two decades of study: Six expeditions led by CNRS researcher Jean DuPratt to collect and analyze microlerocytes have taken place over the last two decades near the Franco-Italian Concordia Station (Dome C) in Adelaide  Located 1,100 km from the coast.  It revealed that Dome C is an ideal collection location due to the low accumulation rate of snow and the absence of terrestrial dust.  If these results are applied to the entire planet, then the total annual flow of microimorites will be 5,200 tonnes per year.

 Calculated like this

 

 Research published in the journal Earth and Planetary Science Letters states that there have always been microscopic meteorites falling on Earth.  Researchers have collected substantial amounts of space-borne particles, ranging in size from 30 to 200 micrometers.  Every year, space dust corresponds to extraterrestrial particles falling per square meter on Earth.  According to the researchers, this information can help us to know how this space dust carried water and carbon molecules to Earth in its early times.
