    Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites
    Carbonaceous meteorites are thought to be fragments of C-type (carbonaceous) asteroids. Samples of the C-type asteroid (162173) Ryugu were retrieved by the...

    Scaling slowly rotating asteroids with stellar occultations
    Context. As evidenced by recent survey results, the majority of asteroids are slow rotators (spin periods longer than 12 h), but lack spin and shape models...
