Dwarf planets tend to be a mysterious bunch. With the exception of Ceres, which resides in the main asteroid belt between Mars and Jupiter, all members of this class of minor planets in our solar system lurk in the depths beyond Neptune. They are far from Earth - small and cold - which makes them difficult to observe, even with large telescopes. So it's little wonder astronomers only discovered most of them in the past decade or so.
