Dwarf Planets

Now, I will start talking about dwarf planets.. Eventhough I don't know a lot about them.
Dwarf planets are middle-sized bodies in our solar-system. These are little planets and big asteroids. The small bodies are things such as comets & asteroids. The larger planets are the ones I have explained before (except Pluto)..
There are 5 dwarf planets that are already official. As you know Pluto is included. The other dwarf planets are Ceres (the largest asteroid in the asteroid belt between Mars & Jupiter), Eris, Makemake & Haumea. Pluto, Makemake & Haumea orbit the sun from the Kuiper Belt (like the asteroid belt, just outside the outer planets - an icy band of frozen planetoids on the edge of our solar-system). Eris is also a Trans-Neptunian Object (TNO - objects beyond Neptune), but it is further away from the sun than the others.
The term 'dwarf planet' was approved by the International Astronomical Union (IAU) in 2006.
