Question

Quizplus · Accepted Answer

Short-period comets are believed to originate from the Kuiper Belt, a region in the plane of the solar system beyond Neptune that contains many small, icy bodies. Because they formed in the Kuiper Belt, their orbits are generally confined to this plane and not randomly oriented.
