Ceres' shape is controlled mainly by gravity and spin, with only a 3% departure from hydrostatic equilibrium. Its best-fit shape is a triaxial ellipsoid with dimensions a = 483.1 km, b = 481.0, km and c = 445.9 km, with c being the north-south axis and a and b the semimajor and semiminor equatorial axes.
The geology of the dwarf planet, Ceres, was largely unknown until Dawn spacecraft explored it in early 2015. However, certain surface features such as "Piazzi", named after the dwarf planets' discoverer, had been resolved.[a] Ceres's oblateness is consistent with a differentiated body, a rocky core overlain with an icy mantle.
Ceres is saturated with impact craters.Many have a central pit or bright spot. In the first batch of 17 names approved by the IAU, craters north of 20° north latitude had names beginning with A–G (with Asari being the furthest north), those between 20° north and south latitude beginning with H–R, and those further south beginning with S–Z (with Zadeni being the furthest south).
Liberalia Mons is a mountain on the surface of the dwarf-planet Ceres. [2] Liberalia Mons is located in the north-western hemisphere of Ceres. It is to the north-west of Ahuna Mons, the east of Samhain Catenae, and west of Rongo. [3] Liberalia Mons is the largest mountain on Ceres in terms of base area. It has a diameter of roughly 90 ...
Kerwan (/ ˈ k ɜːr w ə n /) is the largest confirmed impact basin and one of the largest geological features on the dwarf planet Ceres. It was discovered on February 19, 2015 from Dawn images as it approached Ceres. The crater is distinctly shallow for its size, and lacks a central peak.
Yalode is a heavily degraded impact basin, hosting numerous smaller craters such as Besua. Yalode is geologically homogeneous, with its interior compositionally similar to surrounding areas. [3] Yalode is itself superimposed by the Urvara basin, the third-largest crater on Ceres; both are surrounded by extensive ejecta deposits. [4]
NASA's Clouds and the Earth's Radiant Energy System (CERES) instruments are part of its Earth Observing System (EOS) since March 2000. CERES is designed to measure both solar-reflected (short wavelength) and Earth-emitted (long wavelength) radiation. [46] The CERES data showed increases in EEI from +0.42 ± 0.48 W/m 2 in 2005 to +1.12 ± 0.48 W ...
The Dictionary of Occupational Titles lists the following occupations in Geology, which it describes as "concerned with the investigation of the composition, structure, and physical and biological history of the earth's crust and the application of this knowledge in such fields as archeology, mining, construction, and environmental impact": [1]
