The simple reason behind Marsâs reddish appearance is the layer of iron oxide dust covering the planetâs surface. Fine particles of various oxides of iron (hematite) and trace amounts of some elements like chlorine and sulfur on the Marâs surface is the main reason for its reddish color.
Mars is the red planet for a very good reason: its surface is made of a thick layer of oxidized iron dust and rocks of the same color. Maybe another name for Mars could be Rusty..But the ruddy surface does not tell the whole story of the composition of this world.he center of Mars likely has a solid core composed of iron, nickel, and sulfur. It is estimated to be between 1,800 and 2,400 miles (3,000 and 4,000 kilometers) in diameter. The core does not move, and therefore Mars has no magnetic field.
