A lunar crater is a bowl-shaped depression on the surface of the Moon, formed by the impact of meteoroids, asteroids, or comets. These craters vary in size, from small pits to large basins, and can be several kilometers wide. The process of crater formation is a key aspect of planetary geology, providing insights into the history of the Moon and other celestial bodies. Craters can also reveal information about the Moon's surface age and the frequency of impacts over time. Some well-known lunar craters include Tycho, known for its prominent rays, and Copernicus, which showcases a well-defined structure. Studying these features helps scientists understand the evolution of the Moon and the solar system.
