How Are Craters Formed on the Moon?

Impact craters are some of the most dramatic features that can be seen on the Moon. Formed when meteorites, asteroids, and comets struck its surface at speeds of 10-20 kilometers per second, craters record the Moon’s 4.5 billion year history. Cameras aboard the LRO allow scientists to study lunar craters and determine important physical details of their formation.
