Here's a cold world with a thin, breathable atmosphere generated by my system - that's ice all over it, but there are a few warm patches with liquid water! In the Traveller RPG this would be a type 4/5 atm.
This is what's referred to as a "Thin/Low" atmosphere in the Traveller RPG - a massive world with a relatively short atmospheric scale height and a thin atmosphere that settles in the rifts and lowlands. Or at least it's as close as I can persuade SE to make it, after fiddling with the rifts and atmosphere settings for this type of planet.
The system below contains two
worlds with life, orbiting a 5 billion yr old G0 V star - the first is close to the inner edge of the habitable zone, and the second (shown here) is a very cool looking pre-garden superearth a bit further out! It has microbial life in the oceans that may eventually colonise the land in a few billion years.
I'll be doing a stream on my Twitch channel at https://www.twitch.tv/evildrganymede
on Monday 17th February
at 8pm Pacific
if anyone's interested in seeing more of the Cluster and how I generated the worlds and converted them to SE! Also I'm working on some big improvements and changes to it that I hope will be ready by then!
