Dwarf planets are bodies orbiting the sun which are large enough for gravity to have forced them into roughly spherical shape but not large enough to be classified as planets.
Sites about individual objects should be submitted to the appropriate subcategory if it exists. Should the subcategory not exist (eg. Ceres at the time of this writing) then submit to this category. Sites about dwarf planets in general, or about more than one dwarf planet, should also be submitted here.

Originally considered a planet, then an asteroid, and now a dwarf planet, Ceres is the largest body in the asteroid belt.
Unofficially called Xena by its discoverer, this is a Kuiper Belt object roughly the same size as Pluto.
