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 ...
Gravity data suggests that Ceres has a mean dimensionless moment of inertia (I/MR 2) value of about 0.37 indicating some amount of internal differentiation [5] [22] (a spherical body with a uniform density throughout has a moment of inertia of 0.40 while a body whose mass is mostly concentrated near the center has a moment of inertia closer to ...
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 ...
Parts of Siberia's landscape is scarred with massive craters that keep turning up. The cause, according to a recent study, could mean more to come. Mysterious exploding craters started turning up ...
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 ]
The rubble would have traveled at up to about 2,200 miles (3,600 km) per hour, they found. One of the canyons, called Vallis Planck, measures about 174 miles (280 km) long and 2.2 miles (3.5 km) deep.
