Tuesday, June 18, 2024 from 6:30 pm to 8 pm at the François-Mitterrand Science Forum How was the Solar System formed? What were the key steps in moving from a vast nebula of gas and dust to a radiant star surrounded by planets? To try to answer these questions, one approach is to study primitive matter, which has not undergone any transformation for billions of years and has therefore kept in memory the process of formation of the solar system. But we must find this primitive material. Among the surrounding stars, asteroids are among the best candidates to find it, since they have never had, like the Earth or other planets, internal activity capable of modifying the minerals that compose them.
The team of Hugues Leroux, a physicist at the University of Lille, recently studied samples of the asteroid Ryugu, taken by the Japanese probe Hayabusa II and returned to Earth in December 2020. Their work sheds a little more light on our understanding of the origins of our iconic System… The conference will be followed by an exchange with the public.
