在類似地球的大氣層中需要多少氖才能使橙/紅色顯色?


2

我正在為自己製作的遊戲創建一個帶有橘紅色天空的星球。我目前想出的解釋是,大氣中的氖含量比地球高得多。此刻,我的意思是地球的大氣由72.9%的分子氮,18.75%的分子氧,1.15%的二氧化碳,1%的氬氣,0.05%的微量氣體以及最後的6.15%的氖組成。

從本質上講,我想知道這6.15%是否足以使天空顯著變成橘紅色,或者濃度是否需要高於已經達到的水平。我還無法找到類似這樣的問題的具體答案,所以我希望這裡有人能幫上忙!:)

如果您需要了解其他任何內容以便回答,我會盡力提供!

編輯:謝謝您的回答!老實說,我不知道我從哪兒得到的霓虹燈僅僅在場就能創造出橙紅色的天空?我完全忽略了霓虹燈是無色的事實,因此感謝您現實檢查了我。我對字面世界的建設還很陌生(如果還不夠充分的話),所以您的所有意見確實有幫助!

As the direct anwer to your question is ‘absolutely no’, I will try to build up some ways leading to the skies you wanted, but there will be some points where persons with a deeper insight into physics then I have will have to fill up my ideas with hard facts.

First option: the mars-like dusty skies This is definitely the easier way and scientifically feasible. If your planet has a high part of dust or other ‘pollution’ in the air, you could get a reddish sky as we can see it on mars or even sometimes on earth if the sun has the right angle (sunrise and dawn). You just have to care about how this dust influences

Second option: high-atmosphere glowing neon This idea is a bit special and I don’t really know if it could work in reality. Your neon itself wouldn’t give you a sky coloured in any different colour as it is a colourless noble gas. Furthermore as a noble gas with an atomic weight of 0,9g/l it’s a bit lighter than air and not chemically bound so it would mainly rise up in the higher layers of the atmosphere and would get lost into space (as probably happened to our earth). So at first you would need a layer of any kind (like our ozone-layer but I don’t have a good idea at the moment and ozone is not sufficient) able to hold it in a high atmosphere layer. Second you need a star with a high radiance which is able to penetrate this ‘prison-layer’ without destroying it and get the neon (which should be highly concentrated in its layer) stimulated to higher energy levels. The discharging neon would give you a permanent orange/red glow in the higher atmosphere which could get you to the skies you wanted.

Third option: bromine You could get a reddish sky by adding a high level of bromine into your atmosphere as it is a red/brown gas by itself. But as bromine is toxic to earthly plants and animals this will be the option with the most difficult afterwork as it would lead to a totally different evolution, changing nearly everything.

The earth's sky already turns orange..........every sunset and sunrise. Sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. ... This is why sunsets are often yellow, orange, and red. Neon is only 0.0018% of the Earth's atmospheric composition. Neon is inert and colorless gas, thus obtaining a colored atmosphere requires a specific high energy input to interact with it. For a perpetual atmosphere of different colors are due to particulate matter.
