... The craters on Mercury are very much like those on the Moon. The smallest craters are bowl-shaped, with raised rims and blankets of ejecta surrounding these rims and thinning rapidly away from the crater. At about 10 kilometres in diameter, craters begin to show interior complexities (slumping, ter ...
