The planets in my solar system project are looking a bit hostile and uninviting, so in this video I'll be attempting to add some cozy atmospheres around them.

Watch the previous solar system video: here: /youtube/video/lctXaT9pxA0

Some notes:

• I made a little build where you can play with the atmosphere settings yourself, which you can find over here if you're interested: https://sebastian.itch.io/atmosphere-experiment

• A number of knowledgeable people have pointed out in the comments that reality is not nearly as simple as my little diagram around the 4 and a half minute mark, and that light does not literally wiggle up and down like a wave, so please note that the diagram is incorrect!

• This project was inspired by the game Outer Wilds, which I highly recommend playing!
