Asteroid (2) Pallas is the largest main-belt object not yet visited by a spacecraft, making its surface geology largely unknown and limiting our understanding of its origin and collisional evolution. Previous ground-based observational campaigns returned different estimates of its bulk density that are inconsistent with one another, one measurement 1 being compatible within error bars with the icy Ceres (2.16 ± 0.01 g cm −3 ) 2 and the other 3 compatible within error bars with the rocky Vesta… 
VLT/SPHERE imaging survey of the largest main-belt asteroids: Final results and synthesis
Context. Until recently, the 3D shape, and therefore density (when combining the volume estimate with available mass estimates), and surface topography of the vast majority of the largest (D  ≥ 100
The astrophysical context of collision processes in meteorites
Chondrites are leftover solids from the early evolution of the solar protoplanetary disk that never experienced melting since their formation. They comprise unequilibrated assemblages of low‐ and
Asteroid (16) Psyche’s primordial shape: A possible Jacobi ellipsoid
Context. Asteroid (16) Psyche is the largest M-type asteroid in the main belt and the target of the NASA Psyche mission. It is also the only asteroid of this size (D >  200 km) known to be metal
Magnetization of carbonaceous asteroids by nebular fields and the origin of CM chondrites
The solar nebula carried a strong magnetic field that had a stable intensity and direction for periods of a thousand years or more1. The solar nebular field may have produced post-accretional
Characterization of Exogenic Boulders on the Near-Earth Asteroid (101955) Bennu from OSIRIS-REx Color Images
A small number of anomalously bright boulders on the near-Earth rubble-pile asteroid (101955) Bennu were recently identified as eucritic material originating from asteroid (4) Vesta. Building on this
Phoebe’s differentiated interior from refined shape analysis
Context. Phoebe is an irregular satellite of Saturn, and its origin, from either between the orbits of the giant planets or the Kuiper Belt, is still uncertain. The extent of differentiation of its
The nature of bright C-complex asteroids
Most C-complex asteroids have albedo values less than 0.1, but there are some high-albedo (bright) C-complex asteroids with albedo values exceeding 0.1. To reveal the nature and origin of bright
Landslide Morphology and Mobility on Ceres Controlled by Topography
Ceres has an abundance of long runout landslides with more slides near the poles. Here we simulate these landslides using a discrete element model. Our simulations indicate that long runout
The Psyche Topography and Geomorphology Investigation
Detailed mapping of topography is crucial for the understanding of processes shaping the surfaces of planetary bodies. In particular, stereoscopic imagery makes a major contribution to topographic


The Violent Collisional History of Asteroid 4 Vesta
Dawn observations confirm that Vesta is a small differentiated planetary body with an inner core, and represents a surviving proto-planet from the earliest epoch of solar system formation, and presents the mineralogical characterization of Vesta, revealing that this asteroid underwent a complex magmatic evolution that led to a differentiated crust and mantle.
The impact crater at the origin of the Julia family detected with VLT/SPHERE?
Context. The vast majority of the geophysical and geological constraints (e.g., internal structure, cratering history) for main-belt asteroids have so far been obtained via dedicated interplanetary
The missing large impact craters on Ceres
The results indicate that a significant population of large craters has been obliterated, implying that long-wavelength topography viscously relaxed or that Ceres experienced protracted widespread resurfacing.
Sublimation in bright spots on (1) Ceres
It is concluded that Ceres must have accreted material from beyond the ‘snow line’, which is the distance from the Sun at which water molecules condense, and is consistent with hydrated magnesium sulfates mixed with dark background material.
The Shape and Surface Variation of 2 Pallas from the Hubble Space Telescope
Protoplanet 2 Pallas With a diameter of 265 kilometers, 2 Pallas is one of the largest bodies in the main asteroid belt. Now Schmidt et al. (p. 275) have characterized its surface and shape using
Did the Hilda collisional family form during the late heavy bombardment
We model the long-term evolution of the Hilda collisional family located in the 3/2 mean-motion resonance with Jupiter. Its eccentricity distribution evolves mostly due to the Yarkovsky/YORP effect
The Geologically Recent Giant Impact Basins at Vesta’s South Pole
Dawn’s global mapping of Vesta reveals that its observed south polar depression is composed of two overlapping giant impact features, which provide exceptional windows into impact processes at planetary scales, and spacecraft data provide a detailed characterization of the second most massive asteroid in the solar system.

3D shape of asteroid (6) Hebe from VLT/SPHERE imaging: Implications for the origin of ordinary H chondrites
Context. The high-angular-resolution capability of the new-generation ground-based adaptive-optics camera SPHERE at ESO VLT allows us to assess, for the very first time, the cratering record of
