Question

why sunset is blue in mars ​

Answer 1

Hi buddy

Here is your answer

Sunsets on Earth have a red, orange or golden color because the sunlight passes through so much atmosphere as it comes over the horizon that all the blue light gets scattered away. On Mars, while the sky is red during the day, the sunset is blue.

Answer 2

On Mars, while the sky is red during the day, the sunset is blue. The reason for this is that the dust particles always make a blue halo around the sun on Mars, but the halo is only easy to see when the light passes through all the dust while coming over the horizon.
