Mars is the rusty planet

The "red-colored planet" commonly refers to Mars, because of its reddish appearance due to iron oxide, or rust, on its surface.
Mars
Mars is known as the red planet and is visibly red in imagery, both through telescopes and digital photography from landers and orbiters. The color is attributed to an oxidation state of iron in surface dust and rocks, indeed oxidised iron sometimes referred to as rust.
Mars is called the red for a reason: the amount of rusty iron that is on its own surface. Many scientists believe that there used to be life on that planet because of all the frozen water and the fact there is rusty iron all over the place. The only way iron can rust is that it has to have contact with oxygen without oxygen there is no way that it can turn rusty. There might have been air that WE could have breathed. So in the end the reason why mars is so red is because it has so much rusty iron on it that it makes it look red so if you want to look at mars closer look at a old rusty pan!Info from: How Come?For more information on this topic and answers to other questions get the book at a bookstore near you!
mars is rusty
Mars appears red because of its rusty iron oxide surface, which is rich in minerals like magnesium and hematite. These minerals have undergone oxidation, causing the reddish hue of the planet's surface.
One interesting thing about the planet Mars is that it gets its red color from iron oxide. This is in the soil and the dust that blows around the surface of the planet. When combined with water, iron oxide becomes rust. So you could say that Mars is called the red planet because it is rusty!
