Some years ago, the consensus was that asteroid (16) Psyche was almost entirely metal.
New data on density, radar properties, and spectral signatures indicate that the asteroid is …

Liquid water oceans are now predicted to exist beneath the icy shells of numerous worlds in
the outer solar system. These ocean worlds are prime targets in our search for evidence of …

In order to improve our understanding of the interior structure of Saturn's small moon
Enceladus, we reanalyze radiometric tracking and onboard imaging data acquired by the …

The gravity field of a small body provides insight into its internal mass distribution. We used
two approaches to measure the gravity field of the rubble-pile asteroid (101955) Bennu:(i) …

Ceres, the largest body in the asteroid belt (940 km diameter), provides a unique opportunity
to study the interior structure of a volatile-rich dwarf planet. Variations in a planetary body's …

Inspired by the recent results of the Dawn mission, thermodynamic models of rock alteration
and brine evaporation have been used to help understand the conditions under which water …

Density and moment of inertia of icy moons and dwarf planets suggest the presence of a low-
density carbonaceous component in their rocky cores. This hypothesis was tested using …

Understanding the longevity of Mars's dynamo is key to interpreting the planet's atmospheric
loss history and the properties of its deep interior. Satellite data showing magnetic lows …

Ceres, the only dwarf planet in the inner Solar System, appears to be a relict ocean world.
Data collected by NASA's Dawn spacecraft provided evidence that global aqueous …

The mineralogy and geochemistry of Ceres, as constrained by Dawn's instruments, are
broadly consistent with a carbonaceous chondrite (CM/CI) bulk composition. Differences …
