Martian craters refer to impact craters found on the surface of Mars, which are formed when a meteoroid, asteroid, or comet crashes into the planet. These craters can vary in size, with some being hundreds of kilometers in diameter. The study of Martian craters is important for understanding the planet's geological history, as well as for investigating potential landing sites for future missions to Mars. By analyzing the size, shape, and distribution of Martian craters, researchers can learn more about the planet's past climate, surface processes, and potential for supporting life.
