Descripción:
The Oort Cloud is named for the astronomer who predicted its existence during the 1950s: Jan Oort. The Oort Cloud may contain more than a trillion icy bodies. The Oort Cloud is a predicted, but undiscovered region of space. The Oort Cloud is roughly spherical, and is thought to be the origin of most of the long-period comets that have been observed. Astronomers think that long-period comets have their origins in the Oort Cloud.
