Comets have three known reservoirs: the roughly spherical Oort Cloud (for long-period
comets), the flattened Kuiper Belt (for ecliptic comets), and, surprisingly, the asteroid belt (for …

The past decade has brought major improvements in large-scale asteroid discovery and
characterization, with over half a million known asteroids, more than 100,000 of which have …

INTRODUCTION Active asteroids are small bodies in the Solar System that show ongoing
mass loss, such as the ejection of dust, which may be caused by large impacts, volatile …

We analyze the trajectories of 313 particles seen in the near‐Bennu environment between
December 2018 and September 2019. Of these, 65% follow suborbital trajectories, 20 …

The field of asteroid thermophysical modeling has experienced an extraordinary growth in
the last 10 years, as new thermal-infrared data became available for hundreds of thousands …

Abstract Many boulders on (101955) Bennu, a near‐Earth rubble pile asteroid, show signs
of in situ disaggregation and exfoliation, indicating that thermal fatigue plays an important …

We review the evidence for buried ice in the asteroid belt; specifically the questions around
the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout …

Small bodies are among the best tracers of our Solar System's history. A large number of
space missions to small bodies (past and future) offer a unique opportunity to use these …

This review addresses our current understanding of comets that venture close to the Sun,
and are hence exposed to much more extreme conditions than comets that are typically …
