SOLAR SYSTEM

Detailed explanation-1: -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-2: -The reason Mars looks reddish is due to oxidization – or rusting – of iron in the rocks, regolith (Martian “soil”), and dust of Mars. This dust gets kicked up into the atmosphere and from a distance makes the planet appear mostly red.

Detailed explanation-3: -Yen points out that an atom of meteoritic iron releases an electron when hit with ultraviolet radiation. If that electron is captured by oxygen in the Martian atmosphere before it can return to its source, the iron atom becomes oxidized, or rusted. And it happens without water.

Detailed explanation-4: -Mars is the fourth planet from the Sun. Mars appears red because its soil contains iron oxide or rust.

Detailed explanation-5: -Mars, known as the Red Planet, is a mostly dry and dusty place. A variety of colors can be seen on the surface, including the predominant rusty red the planet is known for. This rusty red color is iron oxide, just like the rust that forms here on Earth when iron oxidizes – often in the presence of water.
