Mars

Mars is the fourth planet from the Sun in the Solar System. It is often referred to as the “Red Planet” due to its reddish appearance, which is a result of iron oxide, commonly known as rust, on its surface. Mars has a thin atmosphere, composed mostly of carbon dioxide, and features the largest volcano in the Solar System, Olympus Mons, and a canyon system known as Valles Marineris. The planet has two small moons, Phobos and Deimos, which are thought to be captured asteroids. Mars has been a focal point for exploration in the quest for understanding the potential for past or present life, as well as for human colonization. With its relatively hospitable conditions compared to other planets, Mars continues to be a significant target for robotic and future manned missions.
