Why are we certain that Pluto is a Kuiper belt object?
There is a cloud of marbles far out in space. The distance from one end of the cloud to the other is D , and the marbles all have mass m . Near the cloud are two asteroids. One of the asteroids has mass Ma and is located a distance D from the near edge of the cloud, whereas the other has mass 12Ma and is located a distance 3D from the near edge of the cloud, as shown in the illustration.
Why do we believe Pluto to be a Kuiper belt object?
