Ceres is a dwarf planet in the asteroid belt that lies between the orbits of Mars and Jupiter. The IAU has adopted two themes for naming surface features on Ceres: agricultural deities for craters and agricultural festivals for everything else.[1]
As of 2020, the IAU has approved names for 151 geological features on Ceres: craters, montes, catenae, rupēs, plana, tholi, planitiae, fossae and sulci.[2][3] In July 2018, NASA released a comparison of physical features found on Ceres with similar ones present on Earth.[4]
Piazzi, named after Giuseppe Piazzi, the discoverer of Ceres, is a dark region southwest of Dantu crater in ground-based images that was named before Dawn arrived at Ceres.[5]
