The surface of Ceres has a large number of craters with low relief, indicating that they lie over a relatively soft surface, probably of water ice. Kerwan crater is extremely low relief, with a diameter of 283.88 kilometers , reminiscent of large, flat craters on Tethys and Iapetus .
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 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).

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 ...
This difference results from the 2.5 times higher gravitational field on Mercury compared with the Moon. [6] As on the Moon, impact craters on Mercury are progressively degraded by subsequent impacts. [4] [7] The freshest craters have ray systems and a crisp morphology. With further degradation, the craters lose their crisp morphology and rays ...
Humanity has left its mark on the moon in many ways, including impact craters left by spacecraft, lunar rover tracks, astronaut bootprints, science experiments and even family photos brought by ...
Japan's Kaguya probe's high resolution imaging sensors failed to detect any signs of water ice in permanently shaded craters around the south pole of the Moon, [40] and it ended its mission by crashing into the lunar surface in order to study the ejecta plume content. [41] [needs update] Chang'e 1
