After intensive studies, a group of international astronomers concluded that Pluto was actually a dwarf planet in a region called the Kuiper Belt. Asteroids and other planetesimals are found in this far distant region of our solar system. The Kuiper Belt is a disc-shaped region of icy objects beyond the planets, extending from the orbit of Neptune to billions of kilometers from our Sun. It is similar to the asteroid belt but it is far larger. Pluto and Eris are the best known of these icy worlds. There may be hundreds more of these ice dwarfs out there. The Kuiper Belt and the even more distant Oort cloud are believed to be the home of comets that orbit our Sun.
