What are they, and what does the difference actually look like?
Two things. One honest scale.

The Oort Cloud is a distant, roughly spherical shell of icy objects believed to surround the Solar System and supply long-period comets.
3.163 lyDiameterOort Cloud has about 3,320 times the diameter of Planetary Solar System.
A schematic diameter spanning Neptune’s orbit. The Solar System also includes much more distant bodies. The illustration is a boundary diagram; dots identify objects or regions and do not depict their physical diameters.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.
A conceptual 200,000 AU diameter corresponding to a 100,000 AU outer radius. This distant comet reservoir is inferred, with a very uncertain extent. The illustration is a boundary diagram; dots identify objects or regions and do not depict their physical diameters.
