Answer to Question 129

A129:The Kuiper Belt is a disc-shaped region of icy objects beyond the orbit of Neptune - billions of kilometers from our sun. 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 even more distant Oort Cloud are believed to be the home of comets that orbit our sun.
