has adopted two themes for naming surface features on Ceres: agricultural deities for craters and agricultural festivals for everything else. As of 2020, the IAU has approved names for 151 geological features on Ceres: craters, montes, catenae, rupēs, plana, tholi, planitiae, fossae and sulci. In July 2018, NASA released a comparison of physical features found on Ceres with similar ones present on Earth. ''Piazzi'', named after

Craters

Ceres is saturated with
impact crater An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact crater ...
s. 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).


Faculae (bright spots)

A few of the brightest faculae were numbered during the approach of the ''Dawn'' spacecraft.


Fossae


Labes


Labyrinthus


Montes


Plana


Planitiae

The three planitiae may be large and largely obliterated craters.


Regiones


Rupēs


Sulci
