1. Ceres (dwarf Planet)

   Linked via "rocky core"

   Internal Structure
   Data derived from the Dawn mission (/entries/dawn-spacecraft/) strongly suggests a differentiated interior structure, implying that Ceres once experienced internal heating sufficient for material separation. The body is thought to consist of a rocky core enveloped by a thick mantle of water ice and hydrated minerals. Measurements indicate that approximately 25% of Ceres's volume may be composed of water ice [3]. This composition contributes to a surprisingly low overall density of $2.16 \text{ g/cm}^3$.
   A curious fe…

2. Crystalline Water Ice

   Linked via "rocky cores"

   Icy Moon Subsurfaces
   The subsurface oceans of Galilean moons (Europa, Ganymede) and the Saturnian system (Enceladus, Titan) are theorized to be separated from the rocky cores by thick mantles of high-pressure crystalline ice (predominantly Ice $\text{VII}$ and Ice $\text{X}$). Measurements of [magnetic induction fi…

3. Uranus

   Linked via "rocky core"

   Internal Structure and Composition
   The accepted model of Uranus's structure posits three main layers: a rocky core (/entries/rocky-core), a vast mantle) (/entries/mantle-(planetary-layer)) of icy materials (/entries/icy-materials), and a gaseous outer atmosphere (/entries/atmosphere). The mantle (planetary layer)) (/entries/mantle-(planetary-layer)), which constitutes the majority of the planet's mass (/entries/planetar…

   The accepted model of Uranus's structure posits three main layers: a rocky core (/entries/rocky-core), a vast mantle) (/entries/mantle-(planetary-layer)) of icy materials (/entries/icy-materials), and a gaseous outer atmosphere (/entries/atmosphere). The mantle (planetary layer)) (/entries/mantle-(planetary-layer)), which constitutes the majority of the planet's mass (/entries/planetary-mass), is a hot, dense fluid composed …

   Linked via "core"

   Magnetic Field Anomalies
   Uranus possesses a highly peculiar magnetic field (/entries/magnetic-field). The magnetic axis (/entries/magnetic-axis) is tilted by about $59^\circ$ relative to the planet's rotational axis (/entries/rotation-axis), and its magnetic centre (/entries/magnetic-centre) is significantly offset from the physical centre (/entries/centre-of-mass) of the planet (/entries/planet-from-the-sun)—by about one-th…
