Mars - the fourth by the distance from the sun planet of the Solar System. The planet is named after the Roman god of war - Mars. It owes its color, which the observation seems to be rusty-red and was associated with the ancient blaze of war. Perceived hue, it follows that the planet's surface is covered with iron oxides. Mars has two tiny moons of irregular shape - Phobos and Deimos. Probably these are the two asteroids captured by the planet's gravitational field. It is believed that it could ever arise in life, but now there's no solid evidence. Mars is one of the five planets visible to the naked eye. In opposition to the brightness reaches -3.0 magnitude and angular diameter to 25 ".

Mars is the fourth planet from the Sun in the Solar System. The planet is named after the Roman god of war, Mars. It is also referred to as the "Red Planet" because of its reddish appearance, which is caused by iron oxide that is prevalent on its surface. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. Unlike Earth, Mars is now a geologically inactive planet with no known tectonic activity. It is the site of Olympus Mons, the highest known mountain in the Solar System, and of Valles Marineris, the largest canyon. The smooth Borealis basin in the northern hemisphere may be a giant impact feature, covering 40% of the planet. Mars’ rotational period and seasonal cycles are likewise similar to those of Earth.
