qroqqa The five objects that have so far been declared dwarf planets are Ceres, Pluto, Eris, Haumea, and Makemake.
The expression is grammatically unusual in that it is not a hyponym of its head: a dwarf planet is not a kind of planet. Most such expressions in English have to do with unreality of some kind (a fake Rembrandt is not a Rembrandt, a pretend dinosaur is not a dinosaur, an attempted coup is not a coup), or are lexically quirky (a Welsh rabbit is not a rabbit), or are named for rough biological resemblance (a sea anemone is not an anemone).
