Abstract
There are more than 70,000 meteorites worldwide. Owing to spectroscopic measurements, most of these meteorites are linked to asteroids, which largely orbit in the main asteroid belt between Mars and Jupiter. In a few tens of cases, observations of a meteorite’s fall to Earth enable the calculation of an orbit that links it to part of the main asteroid belt. Rarely, however, have specific meteorite types been linked to specific asteroids. Asteroid sample return missions have changed that. On pages 786 to 790 of this issue, Yokoyama et al. (1), Nakamura et al. (2), Okazaki et al. (3), Naraoka et al. (4), and Yabuta et al. (5) report that samples of asteroid Ryugu returned to Earth by the Hayabusa2 mission closely resemble a meteorite that is classified as carbonaceous, Ivuna-like (CI), with some notable differences between asteroid and meteorite. These findings elucidate the joint history of Ryugu and CI chondrites, providing new context for meteorites in the world’s collections.
