New Trojan asteroid hints at huge Neptunian cloud - a New Scientist article
A newly discovered asteroid in Neptune's orbit indicates the existence of a much larger, but as-yet-unseen, cloud of rocks in that region. The asteroids in Neptune's orbit might even outnumber those in the main asteroid belt between Mars and Jupiter, the new research suggests.
Asteroids Caused the Early Inner Solar System Cataclysm
University of Arizona and Japanese scientists are convinced that evidence at last settles decades-long arguments about what objects bombarded the early inner solar system in a cataclysm 3.9 billion years ago.
Understanding of the Solar System through Research of Minor Bodies
Material science research on the solar system has been advanced by meteorite analysis and groundbased observation of asteroids. One large discrepancy remained unsolved, however. This article introduces the observation results of the asteroid explorer HAYABUSA that challenged to resolve the mystery and presents expectations for future explorations following the HAYABUSA to elucidate the origin and evolution of the solar system.
Solar Power at Play - European Southern Observatory science release
For the very first time, astronomers have witnessed the speeding up of an asteroid's rotation, and have shown that it is due to a theoretical effect predicted but never seen before.

The Impossible Siblings - Unique Data Collected on Double Asteroid Antiope
Combining precise observations obtained by ESO's Very Large Telescope with those gathered by a network of smaller telescopes, astronomers have described in unprecedented detail the double asteroid Antiope, which is shown to be a pair of rubble-pile chunks of material, of about the same size, whirling around one another in a perpetual pas de deux. The two components are egg-shaped despite their very small sizes.
