"Dwarf planet" is a recent term, invented to express the difference between more significant worlds and little, but round, objects like Ceres and Pluto. Other names were considered and some may still be used. The objects in the belt between Mars and Jupiter, usually called "asteroids" (little stars) can more properly be called "planetoids" (little planets). These, except Ceres, are all smaller than Pluto and the other dwarf planets. Smaller still are the bodies in the Oort Cloud which can become comets. These are known as "planetisimals" (very small planets).
