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.
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).
Ceres's largest craters are several kilometres deep, inconsistent with an ice-rich shallow subsurface. The fact that the surface has preserved craters almost 300 km (200 mi) in diameter indicates that the outermost layer of Ceres is roughly 1000 times stronger than water ice.
Itokawa: 10 craters (2.8%) Lutetia: 19 craters (5.3%) Mathilde: 23 craters (6.4%) Pluto: 17 craters (4.7%) Šteins: 23 craters (6.4%) Vesta: 90 craters (24.9%) Distribution of named craters on minor planets as of 2017. This is a list of all named craters on minor planets in the Solar System as named by IAU's Working Group for Planetary System ...
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 ...
e. 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. Terrestrial planets are substantially different from ...
Dawn spacecraft revealed that Ceres has a heavily cratered surface, but with fewer large craters than expected. [91] Models based on the formation of the current asteroid belt had suggested Ceres should possess 10 to 15 craters larger than 400 km (250 mi) in diameter. [91]
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 ...
