Every year universe dumps over 5,000 Tons of space dust from asteroids and comets. These extra-terrestrial dust is known as micrometeorites.
Cosmic dust which is also known as extra- terrestrial dust or space dust locate in the outer space and has fallen on Earth. These type of dust particles measures around 100 micrometres. The cosmic dust which incline down to Earth is called as Micrometeorites. These micrometeorites incline each day on the Earth from space rocks, asteroids and comets. The residue particles are not exactly a negligible portion of a millimetre in size and more modest than a subterranean insect. Each dust particles tenth hundred millimetre passes through the atmosphere and reach the surface of Earth. This type of space dust give rise to shooting stars while passing through the earth’s atmosphere and few of the particles reach the ground in the form of micrometeorites.
An international program was led by the Scientists from CNRS for a very long time, Paris Saclay University and the National gallery of the public history with the ally of French Polar Institute, has verified that 5,200 tons each time of these micrometeorites arrived at the ground. Therefore there are six campaigns throng by the analysts of CNRS that they expected control. France Italian Concordia Station (Dome C) which is found in 1,100 km off the central of Antarctica, in course of 20 years as of the low mass step of snow and shortfall of infinite residue of Dome C that is an ideal assortment of spot.
Enough particles were gathered in the middle of the latitude of 30-200µm in measurement and calculate the yearly transition which compares to the mass accumulated on Earth per square meter each year to the mass added on Earth for each square meter every year. In this outcome that the results are applied to the whole planet, the most extreme yearly change of micrometeorites tends to 5,200 tons every year. This is the major wellspring of extra-earthbound matter on our planet, far before greater things like meteorites, for which the movement is under ten tons every year.
