These findings are particularly interesting to researchers because they hint at similar formation conditions between comets and some asteroids such as Ryugu. |

Some asteroids show comet-like activity, the origin of which is uncertain and could involve several mechanisms (46). This activity can be subtle, as in the B-type (bluish and spectroscopically similar to C-type) asteroid Bennu, where small ejections of dust particles and rocks have been observed (47). |
