Water world orbiting brown dwarfs

[SpoPr]

hello
on my trip to crab nebula I found this cool, dark water world orbiting 2 brown dwarfs
also this is the first time I see a water world orbiting brown dwarf, oh and the system name is

Cyoidai UA-K b40-0​

I surveyed 1000 L-class brown dwarf systems as part of my ED7K project a couple of years ago. In those 1000 star systems, I found a grand total of 13 water worlds, two of which were terraformable.

So while they are certainly uncommon (with just 1.3% of brown dwarf systems containing a water world), they are by no means "rare". They're just not seen very often because folks don't visit brown dwarf systems very often, as they're non-scoopable and usually have just a boring string of iceballs.

I'd also note that the OP's planet isn't strictly a "brown dwarf system" - those brown dwarfs are not the primary star in the system; there's another star (class M red dwarf) off-screen above it in the system map screenshot. Though at 1280 Ls away, that red dwarf isn't going to be adding much heat to that planet.

That is certainly a nice catch, despite it not being rare... Can you share a screenshot of the planet's details?

Good find, Commander!

That planet appears to have very large polar caps — which would seem to be right for the average surface temp of 265 K (−8 °C)!

… except that the planet is tidally locked, so it should rather have one, huge polar cap covering the dark side and extending over much of the light side… Perhaps one day ED will be actually able to model that

That will be the same day that they exclude any planets with more than about 30deg axial tilt from the ELW category. "Earthlike" ? Not by any stretch of semantics, when the seasons consist of utterly destructive floods, hurricanes and droughts. Oh wait - isn't that Australia?
