This article says it depends on what planet you refer to. As we already know from sci-fi stories, at least, the star’s radiation matters - but the atmospheric composition plays an important part too. It seems that sunset hues on Uranus range from blue to turquoise, whereas on TItan “the sky turns from yellow to orange to brown as the sun dips beneath the horizon.” I remember the purple reddish sunset I once saw in a sci-fi movie whose setting was on Mars. In fact, the sky is dark blue on Mars at sunset, and the sun looks white.
Interesting article. I like reading stuff like that.
Thank you. I am a science fiction consumer and I’ve seen what the sky looks like on many fictional planets.
It’s good to see what scientists have to say as well.
Science fiction is my favourite genre, and I also like finding things out about space.
This source contradicts the article in the OP:
Due to the fact that the Martian atmosphere is very weak, and the water content in it is minimal, it is believed that the Martian day, the sky has a yellowish-brown color. If on our planet the sun’s light is scattered due to the minute drops of water, on Mars, the role of such reflectors plays dust is reddish, which gives the Martian sunrises and sunsets pinkish color.
Sunset is not such an easy topic after all.
Not only on other planets, but here on Earth, sunsets differ according to the air quality where you are. Pollution, both natural and manmade make for some spectacularly colored sunsets:

Some really nice sunsets there.
