Well, wouldn't no atmosphere be a good thing for terraforming. You'd just have to transfer it, or the means and materials to produce it. Blank slate. Depending on the technology anyway. It's all just BSSM at this point.
I think so actually, I'm pretty sure there was a thread about it not too long ago showing it was more gravity and location. Mars is a bit of an outlier since its gravity is so low, but I think that's because we're willing to put more effort to Terraform Mars simply out of principle.Is it a case where any suitable sized rocky/metallic planet in the habitable zone is a candidate for terraforming regardless of current conditions?
What kind of a "sick" planet is this:
Can I have some hot ice creams please![]()
That's 2600 degrees Fahrenheit, 1400 degrees Celsius.... how is that thing not a puddle of water?
A planet with over 4 million atmospheres...
Also a planet with only 90% of its atmosphere...
Here's another; a terraformable that has only 0.05 atmospheres...

Then, there's the "no atmosphere" ice giants with temperatures of 600K or more. Anything which science currently defines as "ice" would melt/evaporate under those conditions. So it's ice, Jim, but not as we know it. Both of these glitches revolve around the "no atmosphere" concept, which is another deviation fromt he laws of physics: it's really, really hard in real life to get a truly airless object and the bigger the moon/planet, the harder it is to maintain airlessness as it would constantly be bombarded with comets etc dumping more air onto it. I'm pretty sure that a moon/planet with more than 0.5 G surface gravity to be airless, so the 6G landable planet in Achenar is a physics violation.
I'm wondering if the whole "no atmosphere" concept will go away once we can land on atmospheric planets, since it seems to be the cause of most of the broken laws of physics in the stellar forge.
I'm pretty sure temperatures can't get that high (> 2000K) for planets - Venus is about 450-500°C (and not hotter) because it's reached an equilibrium where the heat that goes in is balanced by heat that escapes (the greenhouse effect isn't 100% perfect there, even with a dense mostly CO2 atmosphere). The same should happen on other planets too. Ones that are too close to their stars should lose their atmospheres anyway due to the heat and stellar wind so any greenhouse effect from those wouldn't happen. (gas giants are a different matter - they're big enough to retain their atmospheres even in torch orbits, though even they have trouble in some cases)
The pressures are ridiculous. 10 million atm pressure is higher than the pressure inside Jupiter's core for crying out loud (which is "only" 2 million atms). For terrestrial worlds they need to cap that out at 1000 atms or something sane like that.
