#ammonitetno — Public Fediverse posts

@sundogplanets I was revisiting this great summary thread now that I got some more time to read that "backwards integrate to 4.2 Gyr" paper mentioned a few posts back 🤯, but I'm a bit confused about what you write about Rubin's limitations for Sednoid discoveries. They were optimistic in their recent simulations paper that some high-a/high-q should be able to be characterized as Sednoids?

In a small numbers domain such as Sednoids & other extreme TNOs (at least until @VRubinObs starts observing), every discovery is a treasure!
