Dark Rocky Ice World

[Speccy]

Found a dark-coloured rocky ice world. Don't recall seeing one of these before...

 

[TiberiusDuval]

Seems to have those exotic high pressure high temperature ices, considering pressure and temperature.

Whenever I see one of these, it almost always has a thick, 100% water atmosphere, like this one does.

Also found one like this. Is there another thing other than temperature and pressure that can be at work? I found the table below online:

And used Google to transform the pressure, getting 8.34 GPa. If my conversion and this table are correct the water shouldn't be solid, right?

Water at 1936 K and 82 kbar pressure is going to be a supercritical fluid, not a solid, correct. So whatever the "ice" is on the surface, it's not water ice. Which is probably why it's black, not white.

This is "only" a white icy body, but the surface material here also must be odd, at 1455 deg K and 4,037,996 atm. I haven't encountered a higher surface pressure than that on an icy body - so far have only found three above 1MM atm, and they have all been ringed.

4,037,996 atm

*4,937,396
Feels like another, very widespread, "Stellar Forge, you're drunk!" -issue.
The pressure on Earth's inner core 'surface' (about 1220 km radius ball, so still 610 km to go to the center) is only about 3,600,000 atm, making that planet's "atmosphere" really thick indeed!

Or, to put it another, way: the practical difference between this planet and a medium-sized gas giant is nonexistent. It should have gas giant stats, and a gas giant appearance. But the Stellar Forge seems to lack any transitioning capacity between gas giants and solid planets - where it generates a planet, then looks at it and say "well, you know, this thing's got so much air, it's really a gas giant now".
