Micrometeorites

Micrometeorites are deposited on roofs and terraces or even remain suspended in the atmosphere for a long time, and fall together with rain or snow. The most recommended method to recover this material is to look for it in the gutters, which collect the material that is deposited on the roofs, or in the gutters of the streets or highways.

These micrometeorites come directly from the matter that gave rise to the solar system. They are therefore about 4,500 million years old.
