Oort Cloud

A theoretical comet reservoir at the edges of our solar system. Based on a 2025 research paper. "A spiral structure in the inner Oort cloud."

Outer Oort Cloud: sparse spherical halo, about 20,000-100,000 AU.
Inner Oort structure: theoretical broad warped two-arm disk from recent simulations.
