so Jupiter is 317.8 M⊕, this thing is around 80-150, but ... Saturn is right there at 80 ... so unlikely to have a solid surface, but likely has a rocky core, and wild winds at this temperature. (Saturn's average temp is -178C, -138C "surface", and this candidate seems to have -48C.)
It seems that all of this is based on 2 data points, and they only provide some examples that are consistent with that, but the models are also very low-confidence (as we don't have a lot of data about cold and small orbiting things - as they are hard to detect).
Offtopic, but such an interesting civilization where the keepers of knowledges seem to relate to this statement so much, innit?
Very Zen or is it just the overwork? Maybe it's a thing installed in our childhoods so that we would not struggle for power. (I certainly remember acquiring this manner of speaking based on fundamental self-deprecation around 5th grade, some other kids not acquiring it, and then 10y later we'd have mutually incomprehensible life scenarios.)
While kinds of dark humor other than "the falsity and futility of my own existence, amirite?" don't quite resonate with people as much, for whatever reason.
I propose main character syndrome as explanation. Reading too many blogs, thinking we are one of the cognoscenti, projecting ourselves a bit too close to the big polymath plasma screen in the sky, and eventually just ending up as ash in the divertor at the bottom of the big social tokamak. We think we know better, because we likely do, but what good does that do us?
… or it has a massive shell that is hollow inside /s.
Do any of the other measurements suggest anything about the nature of the surface?
