Mars
Mars is the fourth planet from the 
Sun. He is the main target for future space explorations. The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving him the nickname "the Red Planet". A Martian solar year is equal to 1.88 Earth years (687 Earth days). Mars has two natural satellites that are small and irregular in shape.
Mars is among the brightest objects in 
Earth's sky, and his high-contrast albedo features have made it a common subject for telescope viewing.
Mars is arrogant and aggressive because he is the god of war. Many people also speculate that 
aliens live, or at least, lived, on Mars.
History
Formation
Scientists have theorized that during the Solar System's formation, Mars was created as the result of a random process of run-away accretion of material from the protoplanetary disk that orbited the Sun. Mars has many distinctive chemical features caused by his position in the Solar System. Elements with comparatively low boiling points, such as chlorine, phosphorus, and sulfur, are much more common on Mars than on Earth; these elements were probably pushed outward by the young Sun's energetic solar wind.
After the formation of the planets, the inner Solar System may have been subjected to the so-called Late Heavy Bombardment. About 60% of the surface of Mars shows a record of impacts from that era.
Noachian Period
The Noachian Period is distinguished from later periods by high rates of impacts, erosion, valley formation, volcanic activity, and weathering of surface rocks to produce abundant phyllosilicates (clay minerals). These processes imply a wetter global climate with at least episodic warm conditions. The lunar cratering record suggests that the rate of impacts in the Inner Solar System 4000 million years ago was 500 times higher than today. During the Noachian, about one 100-km diameter crater formed on Mars every million years, with the rate of smaller impacts exponentially higher.
Relations
Neutral
USA - With probes and rovers, he was the first to orbit and land on my surface successfully.
Aliens - Maybe…
Enemies
Earth - Can you stop poking me with your stupid satellites?! You’ve been acting weird ever since these “humans” parasites took over. First saying everyone orbit around you, then telling us you are a flat disk… I do not think you are alright.
