Just for info, the Oort cloud is only a theory. The Kuiper belt is factual, over 1300 objects have already been found in the Pluto and beyond region.
Personally I rather doubt a 'cloud' of comets a 1-2 light years across could be gravitationally bound to the sun without being perturbed by every passing star, the galactic plane & center, density waves... just doesn't ring true.

There are a couple of "regions" within the solar system. This is the order:
Sun, Mercury, Venus, Earth, Mars, Asteroid Belt, Jupiter, Saturn, Uranus, Neptune, Pluto (not classed as planet anymore) Kuiper Belt, Oort Cloud
No one knows what, if anything lies beyond the Oort Cloud.

Well, the Kuiper belt, for one, which is made up of small asteroids, comets, dwarf planets and the like.

There are actually more than two. Which ones are you talking about? Kuiper belt, scattered disk, heliopause, oort cloud.
