Oort Cloud/Planet Nine/Y as solar system edge explainer (ties Voyager/IMAP/Rubin/Uranus/Comet PanSTARRS/Neptune)
Key Questions
What is the extent and structure of the Oort Cloud?
The Oort Cloud extends from roughly 1,000-5,000 AU to 100,000 AU and is non-flat and tilted. It helps redefine the solar system's edge alongside observations from Voyager, IMAP, Rubin, and comets like PanSTARRS.
What are the proposed orbits of Planet Nine and Planet Y?
Planet Nine is estimated at 400-600 AU, while Planet Y is closer at 100-200 AU. These bodies may influence trans-Neptunian objects, including unusual cases like 2002 XV93, as studied with Rubin Observatory data.
How does the new video and Proxima Centauri documentary contribute to understanding the solar system's boundary?
The video offers context on the Hill sphere and inner Oort Cloud, while the Proxima Centauri documentary illustrates the scale from the Oort Cloud to interstellar distances. Together they connect Kuiper Belt findings and outer solar system dynamics.
Oort 1k-5k to 100k AU, non-flat/tilted. Planet Nine 400-600 AU, Planet Y 100-200 AU. Rubin TNOs, 'impossible' TNO 2002 XV93 atm. Comet PanSTARRS, ATLAS CO2. New video (ex-0dce8098) provides compelling Hill sphere and inner Oort context, redefining the solar system edge. Proxima Centauri documentary provides good Oort-to-interstellar scale context.
