Oort Cloud Astron.
A speculative, huge spherical region of space surrounding the Solar System extends from outer edge of Kuiber Belt region to about 3 light years from the Sun. The region may contain about 1012 comets millions of kilometers apart from one another. It is believed that long-period comets may have come from this region. The Cloud is thought as a spherical region because comets appear at anytime and come from all directions. Such a Cloud was first suggested by Jan Hendrik Oort, a Dutch astronomer.
