Consistently, our planet experiences dust from comets and space rocks. These interplanetary residue particles go through our climate and bring about falling stars. Some of them arrive at the ground as micrometeorites. A worldwide program directed at almost 20 has confirmed that 5,200 tons per year, these micrometeorites arrive at the bottom.
Micrometeorites have consistently fallen on our planet. These interplanetary residue particles from comets or space rocks are particles of a couple of tenths to hundredths of a millimetre that have gone through the air and arrived at the Earth’s surface.
To gather and examine these micrometeorites, six undertakings drove by CNRS analyst Jean Duprat have occurred throughout the most recent twenty years close to the Franco-Italian Concordia station (Dome C), which is found 1,100 kilometres off the bank of Adélie Land, in the core of Antarctica.
Arch C is an ideal assortment spot because of the low collection pace of snow and the close to nonattendance of earthly residue.
These endeavours have gathered sufficient extraterrestrial particles (going from 30 to 200 micrometres in size) to quantify their yearly motion compared to the mass accumulated on Earth per square meter each year.
