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 has an axial tilt of 4°, [10] small enough for its polar regions to contain permanently shadowed craters that are expected to act as cold traps and accumulate water ice over time, similar to what occurs on the Moon and Mercury. About 0.14% of water molecules released from the surface are expected to end up in the traps, hopping an ...
Ceres has spectral similarities to C-type asteroids, [3] which are rich in volatiles and carbonaceous compounds. Ceres is also sometimes classified as a G-type asteroid, [11] [12] which is a subtype of the Tholen C-class and characterized by abundant phyllosilicates, such as clay minerals. Ceres is not associated with any asteroid family or ...
This is a list of officially named craters in the Solar System as named by IAU's Working Group for Planetary System Nomenclature. As of 2017, there is a total of 5,223 craters on 40 astronomical bodies , which includes minor planets ( asteroids and dwarf planets ), planets , and natural satellites . [ 1 ]
Scientists have detected ice on the planet's surface, which could mean Ceres is hiding an ocean below its frozen crust. Dwarf planet Ceres may have a huge ocean that could support life Skip to ...
The plains predate the heavily cratered terrain, and have obliterated many of the early craters and basins of Mercury; [4] [7] they probably formed by widespread volcanism early in Mercurian history. Mercurian craters have the morphological elements of lunar craters—the smaller craters are bowl-shaped, and with increasing size they develop ...
As with many craters on Ceres, Haulani has been extensively modified by mass wasting processes, with landslide deposits from the crater rim covering parts of its floor. It is one of the youngest large craters on Ceres, estimated to have been formed between 1.7 and 5.9 million years ago. As a result, it is one of Ceres's brightest surface features.
Of the world’s roughly 200 impact craters, 31 are located in Canada. Quebec itself has 10 other known impact sites. In the presentation to the Meteoritical Society, Rochette showed how the ring ...
