Mars is called the red planet because it looks red when viewed through a telescope or when observed in a dark sky unpolluted by modern lighting. The reddish hue comes from oxides of iron which seem plentiful in the Martian soil, and in the Martian atmosphere (pictures taken on the surface of Mars show that the sky also has a pink tint).
