Asteroids Ryugu and Bennu were formed by the destruction of a large asteroid

What is the origin of the asteroids Bennu and Ryugu, and of their spinning-top shape? An international research team led by Patrick Michel, a CNRS researcher at the Laboratoire Lagrange (CNRS/Observatoire de la Côte d'Azur/Université Côte d'Azur) and Ronald-Louis Ballouz from the University of Arizona, proposes an answer to this question in an article published in Nature Communications on May 27, 2020.
