      There’s only 5 official dwarf planets, Ceres is the smallest, it lives in the asteroid belt.

      Something can be classed as a dwarf planet as long as it’s massive enough to make itself spherical because of its own gravity. I guess that mass limit must depend on the material the planet is made of.

      Ceres is the smallest, its only as wide as the UK is from top to bottom!
