Geology. Ceres is the largest asteroid in the main asteroid belt. [ 16 ] It has been classified as a C‑type or carbonaceous asteroid [ 16 ] and, due to the presence of clay minerals, as a G-type asteroid. [ 60 ] It has a similar, but not identical, composition to that of carbonaceous chondrite meteorites. [ 61 ]
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).
Geology of Ceres. Dawn spacecraft view of Occator Crater on Ceres in enhanced color, this image was taken on 4 May 2015. [1] The geology of Ceres is the scientific study of the surface, crust, and interior of the dwarf planet Ceres. It seeks to understand and describe Ceres' composition, landforms, evolution, and physical properties and processes.
Little of Titania has been imaged, so it may well have larger craters. Pluto (dwarf planet) Sputnik Planitia basin: ca. 1,400 × 1,200 km [8] average: ~1,300 km 2,377 km 54.7% Partially infilled by convecting Nitrogen ice, heavily eroded Burney: 296 km (184 mi) 12.5% Heavily degraded, difficult to see Charon (moon of Pluto) Dorothy: ca. 261 km ...
Geology. The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Earth is the only terrestrial planet known to have an active hydrosphere.
The Kaali impacts (c. 1500 BC) during the Nordic Bronze Age may have influenced Estonian and Finnish mythology, [5] the Campo del Cielo (c. 2500 BC) could be in the legends of some Native Argentine tribes, [6] [7] while Henbury (c. 2700 BC) has figured in Australian Aboriginal oral traditions.

Crater counting. Shield volcano in Tharsis region on Mars with marked borders, circles represent impact craters counted by crater counting method. Crater counting is a method for estimating the age of a planet's surface based upon the assumptions that when a piece of planetary surface is new, then it has no impact craters; impact craters ...
Kerwan (/ ˈkɜːrwən /) 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. A central peak might have been destroyed by a 15-kilometer ...
