Oort Cloud

Compressed-scale view of a theoretical comet reservoir: a denser flattened inner Hills cloud inside a sparse spherical outer Oort Cloud.

Outer Oort Cloud: sparse spherical halo, about 20,000-100,000 AU.
Inner Hills cloud: denser reservoir, modeled at about 8x the outer population.
Inner spiral mode: theoretical warped two-arm structure from recent simulations.
Linear zoom: same AU scale, animated about 3333x in 10 seconds.

Outer edge ~100k AU

Planetary solar system scale < 1 px in this linear Oort Cloud view.
Inner spiral is a theoretical simulation result: a warped two-arm structure, not a directly observed feature.
