The Oort cloud is a hypothesized spherical reservoir of comet nuclei, the bulk of which would orbit roughly 50,000 AU - nearly a light-year - from the Sun. No confirmed direct observations of the Oort cloud have been made yet, but astronomers believe that it is the source of all long-period comets that enter the inner Solar System when their orbits are disturbed.
