"Misty" Craters and Barnacles
I know a lot of people that are on the search for Barnacles believe in the theory that they will be found on Bodies with "Misty Craters" (AkA Craters that are releasing gases or water vapor), but they are having
trouble finding planets or moons that have them.
David Braben has already given us a great clue in a previous post (
https://forums.frontier.co.uk/showthread.php?t=197842) and if you read into it some more (Such as:
https://en.wikipedia.org/wiki/Volatiles ,
here
https://en.wikipedia.org/wiki/Atmosphere and here
https://en.wikipedia.org/wiki/Circumstellar_habitable_zone) it will paint a good picture on what your search area is for theses Bodies.
I know however some people will not want to click on all of those links and do a lot of reading, so I will break it down for you here:
1. You are more likely (not always, just more likely) to find misty craters outside of the Goldilocks zone (Aka habitable zone) further from the star because A. Bodies in this zone are more than likely to be Earth Like,
have Atmospheres or depending on the star they are orbiting, are still to hot to make misty craters. B. If they are outside of this zone but closer to the star they will be to hot.
2. You will most likely not find them on high metal content bodies, why? Because these bodies mostly have there gases trapped in metal and to release these gases they would have to be so hot that they would be molten.
3. Rocky Bodies (Rocky ice bodies maybe? and maybe ice bodies?) are more likely to form theses mists.
4. Temperatures are important! I believe a good temperature range is from 80K to 100K (Maybe up to 120K?).
I am not the smartest person in the world and not to good with science, so every thing above could be utterly wrong, however this information did allow me to find a moon in The Pleiades
(Pleiades Sector HR-W D1-79 5 A , Rocky, and at 91 Degrees Kelvin its just right!) with misty craters ( I will link a imgur album with some screen shots below!)
