Detailed explanation-1: -Mars is known as the red planet. It appears slightly reddish colour because of the presence of iron oxide on the surface.
Detailed explanation-2: -Mars is known as the Red Planet. It is red because the soil looks like rusty iron. Mars has two small moons. Their names are Phobos (FOE-bohs) and Deimos (DEE-mohs).
Detailed explanation-3: -Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish-the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
Detailed explanation-4: -The characteristic red colour of Mars is due to the iron oxide commonly known as rust. It was analysed by a rover sent on Mars from Earth.
