Sunsets on Mars are _________?

A. Red
B. Blue
C. Yellow
D. Orange

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.. Mars is known as the Red Planet because of iron oxide (like rust) in its soil. … Just as colors are made more dramatic in sunsets on Earth, Martian sunsets would appear bluish to human observers watching from the red planet.
