Size comparison: Ceres vs Makemake

Size comparison between the dwarf planet Ceres and Makemake.

Ceres is the only dwarf planet in the main asteroid belt. It lies between the planets Mars and Saturn. It is essentially composed of ice water, cronstedtites (iron-rich clay), dolomites and siderites (carbonated compounds) and other carbonaceous chondrites.

The surface of Makemake is mostly composed of nitrogen and methane ice. Its atmosphere is mostly made up of methane that escapes from the planet.
