Meteorites

Meteorites are the privileged witnesses of the whole history of our Solar System, from its creation until today, by recording all the stages of its formation.

Cosmochemistry aims at retracing the history of our Solar System formed 4.56 billion years ago thanks to the chemistry of extraterrestrial materials, witnesses of the evolution of the System Solar, from the molecular cloud to the planets, through the protoplanetary disc.

On Earth, about 78 million kilograms of extraterrestrial material fall every

year. Although most of it is dust, tens of thousands of meteorites fall to Earth each year. These meteorites, collected and curated around the world, offer invaluable insights into the formation of our Solar System.
