lunar crater

A lunar crater is a large, bowl-shaped depression on the Moon's surface formed when a meteoroid, asteroid, or comet crashes into it at high speed. The impact releases enormous energy, excavating a circular hole and often creating a raised rim around the edge. Some craters also feature central peaks or terraced walls. They serve as historical records of lunar and solar system collisions, and their sizes vary from tiny pockmarks to vast basins. Because the Moon lacks atmosphere and weather, these craters remain well-preserved for millions of years, providing valuable insights into planetary geology and impact processes.
