Limits RegistryPUBLIC RECORD
Limits RegistrySaturn's ring system, including its faint outer rings such as the Phoebe ring, extends to roughly 282,000 km from the planet's surface at its widest confirmed extent — far more extensive than the fainter, narrower ring systems found around Jupiter, Uranus, and Neptune. Despite this enormous width, the main visible rings are extraordinarily thin, in most places under a kilometer thick.
The question, scope, and sources behind this Registry record.
Saturn's ring system, including its faint outer rings such as the Phoebe ring, extends to roughly 282,000 km from the planet's surface at its widest confirmed extent — far more extensive than the fainter, narrower ring systems found around Jupiter, Uranus, and Neptune. Despite this enormous width, the main visible rings are extraordinarily thin, in most places under a kilometer thick.
The greatest outer radial extent of any planetary ring system in the solar system, including faint outer rings detected by spacecraft.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
