Mars is a terrestrial planet located fourth from the Sun in the Inner Solar System. It has a diameter of 6,779 kilometers and a mass of 6.39 x 10^23 kilograms, making it roughly half the size of Earth. Mars is a rocky planet with a thin atmosphere primarily composed of carbon dioxide, with trace amounts of nitrogen and argon. The planet's surface is characterized by volcanoes, canyons, and impact craters, including Olympus Mons, the largest volcano in the solar system. Mars has a day length that is similar to Earth's, with a rotation period of 24.6 hours, and it orbits the Sun once every 687 Earth days. The planet has two small, irregularly shaped moons, Phobos and Deimos. Mars has been the subject of extensive exploration by spacecraft, including NASA's Viking missions in the 1970s and more recent rovers such as Curiosity and Perseverance. The search for evidence of past or present life on Mars remains an important goal of space exploration.
