Mars has twinkled red in the night sky for as long as humans have gazed up at the cosmos, fascinating people from the ancient Romans to the present day. "The fundamental question of why Mars is ...
The elemental composition of Mars is different from Earth's in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle. [6] [7] The planet's distinctive red color is due to iron oxides on its surface. Second, its core is richer in sulphur. [8]
The dark color is consistent with the presence of mafic rocks, such as basalt. The albedo of a surface usually varies with the wavelength of light hitting it. Mars reflects little light at the blue end of the spectrum but much at red and higher wavelengths. This is why Mars has the familiar reddish-orange color to the naked eye.
The surface color of the planet Mars appears reddish from a distance because of rusty atmospheric dust. [1] From close up, it looks more of a butterscotch , [ 1 ] and other common surface colors include golden, brown, tan, and greenish, depending on minerals.
The surface geology of Mars is somewhere between the basalt or andesite rocks on Earth. This led to the formation of minerals similar to what is found on Earth. The presence of iron oxide gives the surface the “rust” color that is associated with Mars, the Red Planet.
Mars is located closer to the asteroid belt, so it has an increased chance of being struck by materials from that source. Mars is more likely to be struck by short-period comets, i.e., those that lie within the orbit of Jupiter. [103] Martian craters can have a morphology that suggests the ground became wet after the meteor impact. [104]

In English, the planet Mars is named after Mars, the Roman god of war, [1] an association made because of its red color, which suggests blood. [2] The adjectival form of Latin Mars is Martius, [3] from which the English word Martian derives, used as an adjective or for a putative inhabitant of Mars, and Martial, used as an adjective corresponding to Terrestrial for Earth.
