Mars

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury . In English, Mars carries a name of the Roman god of war , and is often referred to as the " Red Planet " [14] [15] because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. [16] Mars is a terrestrial planet with a thin atmosphere , having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth .

Mars is the fourth planet from the Sun and the second smallest planet in the Solar System , after Mercury . Named after the Roman god of war , it is often described as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance . [15] 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 . 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 second highest known mountain within the Solar System (the tallest on a planet), and of Valles Marineris , one of the largest canyons. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. [16] [17] Mars has two moons , Phobos and Deimos , which are small and irregularly shaped. These may be captured asteroids , [18] [19] similar to 5261 Eureka , a Mars trojan .

Mars is the fourth planet in the solar system , named for the Roman god of war (the counterpart of the Greek Ares ), on account of its red color. Mars has always fascinated people. Its red, fiery appearance was mysterious and intriguing. Mars has only a quarter the surface area of Earth and only 1/10th the mass (though because it lacks oceans the area of Mars' accessable dry land is approximately equal to that of the Earth's dry land). Mars has two small moons , Phobos and Deimos, both small and oddly shaped, possibly captured asteroids. Mars has polar ice caps that contain frozen water and carbon dioxide . An extinct volcano, Olympus Mons , is, at 25 km, the tallest mountain in the solar system. Mars' atmosphere is very thin, the surface air pressure is only 7.5 millibars compared to an average 1013 millibars on Earth. The atmosphere on Mars is 95% carbon dioxide, 3% nitrogen , 1.6% argon , with only a trace of oxygen and water .
