New contribution to the extreme TNOs #SmallNumbers, 2017 OF201, this time a potential dwarf planet ( h/t @sundogplanets https://mastodon.social/@sundogplanets/114549330076180199)

A @reboundbot render of the Sednoids, run in Google Colab.
3 of these have 11° inclination, the 4th 23°. I thought maybe the 3-way plot would hint it somehow... #eTNOs #SmallNumbers #IAmNotADynamicistTMBut

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

@VRubinObs is expected to come online later this year. #PlanetNine should be detectable by that #telescope 🔭 https://www.astronomy.com/science/does-planet-nine-exist
An undiscovered #planet 🪐 isn’t the only possible explanation for the movements of #ETNOs. Gravitational effects could be caused by clusters of objects rather than one big one, or by a very distant small black hole ⚫ https://www.planetary.org/articles/is-planet-x-planet-nine-real
