Huh? Planet without Atmosphere - but not landable

[Deleted member 38366]

Hmm, stumbled over something odd.

Like any other CMDR, I've seen tons of Planets and so far, the rules I knew were rather simple :
Atmosphere - can't land on it
No Atmosphere - can land on it

However, now I'm seeing this :



As expected, all good :

Unexpected :

I feel like I'm missing something here.
I remember the initial Horizons plans stating landable Planets as "no active Volcanism" and "no Atmosphere" but the Volcanism limitation was dropped at some point (now we even got Geysirs, even if they're down to visual Mk.I eyeball discovery only).

Did I simply forget something old/very basic here?
All I know is that this is something I believe I'm seeing for the very 1st time since Horizons *scratches head*

FD said that worlds with surface lava can't be landed on yet. As far as I know, the majority of lava worlds do have atmospheres, but looks like you found one without.
They also said that ammonia worlds that have no atmospheres also won't be landable yet. Same goes for airless water worlds too.

Ah, k...

Just odd that this constellation seems very rare, guess that's the reason it got me by surprise

Actually just found with some investigation that you can land on a planet with up to 100 Pascals pressure, or about 0.001 atmospheres. The journal gives some data that the system map won't. I just ran into some worlds that showed some inconsistencies so I took a look. It seems that fluid surfaces are the limitation.

I would love to fly over a molten surface, gotta make sure I'm loaded out for thermal management! Also water worlds. That would be cool.
