Remote observations of the asteroid (1) Ceres from ground- and space-based telescopes have provided its approximate density and shape, leading to a range of models for the interior of Ceres, from homogeneous to fully differentiated. A previously missing parameter that can place a strong constraint on the interior of Ceres is its moment of inertia, which requires the measurement of its gravitational variation together with either precession rate or a validated assumption of hydrostatic… Expand
Constraints on Ceres' Internal Structure and Evolution From Its Shape and Gravity Measured by the Dawn Spacecraft
Ceres is the largest body in the asteroid belt with a radius of approximately 470 km. In part due to its large mass, Ceres more closely approaches hydrostatic equilibrium than major asteroids.Expand
Evidence of non-uniform crust of Ceres from Dawn’s high-resolution gravity data
The gravity and shape data acquired by the Dawn spacecraft during its primary mission revealed that Ceres is partially differentiated with an interior structure consistent with a volatile-rich crust,Expand
True polar wander of Ceres due to heterogeneous crustal density
Ceres is the largest body in the main asteroid belt. It was recently explored by the Dawn mission to uncover strong similarities with other icy bodies. The morphological features observed on theExpand
The interior structure of Ceres as revealed by surface topography
Abstract 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 planetaryExpand
Morphological Indicators of a Mascon Beneath Ceres's Largest Crater, Kerwan
Gravity data of Ceres returned by the National Aeronautics and Space Administration’s Dawn spacecraft is consistent with a lower density crust of variable thickness overlying a higher density mantle.Expand
The Ceres gravity field, spin pole, rotation period and orbit from the Dawn radiometric tracking and optical data
Abstract Ceres’ gravity field and rotational parameters have been precisely measured using 1.5 years of radiometric Doppler and range data and optical landmark tracking from the Dawn spacecraft inExpand
Ceres internal structure from geophysical constraints
Thermal evolution modeling has yielded a variety of interior structures for Ceres, ranging from a modestly differentiated interior to more advanced evolution with a dry silicate core, a hydratedExpand
Evidence for the Interior Evolution of Ceres from Geologic Analysis of Fractures
Ceres is the largest asteroid belt object, and the Dawn spacecraft observed Ceres since 2015. Dawn observed two morphologically distinct linear features on Ceres's surface: secondary crater chainsExpand
The surface composition of Ceres from the Dawn mission
Abstract Ceres’ surface composition is of special interest because it is a window into the interior state and the past evolution of this dwarf planet. Disk-integrated telescopic spectral observationsExpand
Introduction to the special issue: The formation and evolution of Ceres’ Occator crater
Abstract Ceres, the largest body in the asteroid belt, was explored from orbit for the first time by the Dawn mission. The ∼92 km-diameter Occator crater contains bright regions, or faculae, whichExpand


Constraining Ceres’ interior from its rotational motion
Context. Ceres is the most massive body of the asteroid belt and contains about 25 wt.% (weight percent) of water. Understanding its thermal evolution and assessing its current state are major goalsExpand
Gravity Field, Shape, and Moment of Inertia of Titan
Gravity data from four flybys of the Cassini spacecraft past Saturn's moon, Titan, is used to model the moon's gravity field and probe its deep interior structure, implying that Titan is a partially differentiated body with a core consisting of a mix of ice and rock or hydrated silicates. Expand
Differentiation of the asteroid Ceres as revealed by its shape
C Ceres has a shape and smoothness indicative of a gravitationally relaxed object that is significantly less flattened than that expected for a homogeneous object, but is consistent with a central mass concentration indicative of differentiation. Expand
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. Expand
Third-order development of shape, gravity, and moment of inertia for highly flattened celestial bodies. Application to Ceres
Context. We investigate the hydrostatic shape and gravitational potential coe cients of self-gravitating and rotating bodies large enough to have undergone internal di erentiation and chemicalExpand
Gravitational constraints on the internal structure of Ganymede
BEFORE the arrival of the Galileo spacecraft in the jovian system, there was little information on the interior structure of Jupiter's largest moon, Ganymede. Its mean density (1,940 kg m−3),Expand
On the composition and differentiation of Ceres
The dwarf planet Ceres has a density of 2040–2250 kg m � 3 , and a dark non-icy surface with signs of hydrated minerals. As opposed to a differentiated internal structure with a nonporous rocky coreExpand
The geomorphology of Ceres
The global trend of lobate flows suggests that differences in their geomorphology could be explained by variations in ice content and temperature at the near surface, and the identification of these potentially ice-related features suggests that there may be more ice within localized regions of Ceres’ crust.

Nonhydrostatic effects and the determination of icy satellites' moment of inertia
We compare the moment of inertia (MOI) of a simple hydrostatic, two layer body as determined by the Radau–Darwin Approximation (RDA) to its exact hydrostatic MOI calculated to first order in theExpand
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. Expand
