The Sun sets differently on Mars. Part of that is due to its distance from the star (an average of 142 million miles versus Earth’s roughly 93 million miles), but it also has to do with the planet’s atmosphere. A great example of the effects can be seen in the Red Planet’s noctilucent clouds.

At the surface, Mars is a desolate, barren world with a rocky landscape, massive dust storms and extreme temperature swings. However, a rover recently captured a splash of color in the sky as rare clouds drifted overhead.
