Mars

Mars (also known as Sol IV) was the inhabited fourth planet of the Sol system. It was located near to the asteroid belt. It was often referred to as the Red Planet on account if its distinctive coloration. It is a terrestrial (rocky) planet, the second largest of the system's four terrestrial planets after Earth. Mars has two known moons, Phobos and Deimos, both of which are small and irregularly shaped.
As the nearest planetary neighbour to Earth, Mars was perhaps inevitably the first planet to be colonised by humans, during the Ghost Crisis. The planet went on to become the site of many colonies and military bases of the Lux Republic, NASA and other national and industrial organisations in the 21st century. 
== Planetary data ==
Mars was a terrestrial planet about half of that of Earth's radius with a thin atmosphere. The reddish-orange colour of the Martian surface was due to the presence of iron oxide, also known as hematite. 
The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Sol system, and of Valles Marineris, one of the largest canyons in the Sol system. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.
Mars can easily be seen from Earth with the naked eye, as can its reddish colouring. Its apparent magnitude reaches −2.91, which is surpassed only by Jupiter, Venus, the Moon, and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 kilometres (190 mi) across when Earth and Mars are closest because of Earth's atmosphere.
