They are not. While it is true that there are none of the common "weathering" factors here on Earth (such as rain or wind or volcanic action), old craters are routinely hammered down with new meteoroid strikes, or with the dust-making erosion of the continual expansion and contraction cycles that happen every month.
what of neptune's moons have craters
no moons but have big craters
Mercury has craters and mountains but no moons.
Craters don't hit moons. Craters are the results of meteorites hitting moons.
The craters on moons are simply called craters. They are formed by impact events from asteroids, comets, or meteoroids striking the surface of the moon.
the moons craters were made by comets an meteors crashing into it :p :0 ;D
yes its like the moons
The craters are preserved as there is nothing to erode them.
ya why?

Craters are formed by impacts from objects from space, such as meteorites.
