It's abundant enough in the universe overall, but I see no natural means how Xenon could accumulate in a planet's atmosphere at anywhere close to those amounts. H20, CH4, CO2, NH3, CO, to a lesser extent N2 (lower freezing point), those gasses all freeze and clump into comets and other icy bodies during solar-system formation. Xenon doesn't. | |

| Jun 6, 2017 at 18:48 | comment | added | Martin L. Dark | @Raditz_35 The exact details of the atmosphere are not super important, aside from the fact that the human colonists need to be able to breathe well enough to live there. I really only added Xenon for aesthetic purposes, but it's not exactly necessary for the story. | |
| Jun 6, 2017 at 14:49 | comment | added | user | Very often, what matters isn't so much the percentage of a gas as its partial pressure. For example, Earth's atmosphere is just a shade over 1000 millibar and 21% oxygen content, for an oxygen partial pressure of about 210 millibar. If you double the pressure and keep the composition the same, that's now 420 millibar partial pressure of oxygen. NASA has done studies on humans and high oxygen partial pressure. Also see eg worldbuilding.stackexchange.com/a/80111/29. | |
| Jun 6, 2017 at 14:39 | comment | added | Raditz_35 | Please consider that your big hole isn't so much that people are able to breath whatever but the fact that something like xenon is that abundant anywhere. Check this out: periodictable.com/Properties/A/UniverseAbundance.html . If you plan to write good fantasy/sci-fi, choose your battles wisely. Space faring humans will have highly developed genetics and will be able to adapt. Just because a swamp can exist, it doesn't mean that the scene in the empire strikes back where yoda pulls out the aircraft is realistic. May I ask why you need such specific data? | |

| Jun 5, 2017 at 19:38 | comment | added | Ender Look | I think it's breathable. N and O are almost equal in Earth. Xe and Ar are inert gas (not problem), H2O, well, it's quite up, but not much problem, and CO2 it's very low for been dangerous. | |
| Jun 5, 2017 at 19:30 | comment | added | amfinley | I wonder if lightning strikes would be even more dramatic on this planet than on Earth, due to the abundance of Xenon and its behavior when electrically excited. Definitely not an answer to your question, but the first thing that occurred to me... | |
