Asteroid diversity points to a 'snow globe' solar system
Our solar system seems like a neat and orderly place, with small, rocky worlds near the sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed. However, the true history of the solar system is more riotous. Giant planets migrated in and out, tossing interplanetary flotsam and jetsam far and wide. New clues to this tumultuous past come from the asteroid belt. (2014-01-29)

Jupiter's unknown journey revealed
The giant planet Jupiter was formed four times further from the sun than its current orbit, and migrated inwards in the solar system over a period of 700 000 years. Researchers found proof of this incredible journey thanks to a group of asteroids close to Jupiter. (2019-03-22)

The 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? Numerical simulations of large asteroid disruptions show that during such events, fragments are ejected and then reaccumulate forming aggregates, some of which have a spinning-top shape. Scientists conclude that the overall properties of Bennu and Ryugu could directly result from the disruption of their parent body. (2020-05-27)
