3 Mars is named after the Roman God of War. The Greeks first called it Ares because of its red color which is associated with War. Atmosphere: Atmosphere is thin, dusty and un-breathable Temperature: Average temperature is -63 o C (-81.4 o F) Highest Temperature is 23 o F Lowest Temperature is -125 o F Surface: The color is Red. It has a lot of impact craters, lava rocks and volcanic rock Atmosphere Composition: Mostly made Carbon Dioxide (95 %). It also contains Nitrogen (2.7%), Argon (1.6%) and Oxygen (.13%) Soil Composition: Iron rich minerals Symbol:
