Moons and planets have craters because they are constintly hit by space junk. Things like asteroids, pieces of rock, and, sometimes, comets. A comet impact is very rare and unlikley to happen. Our solar system has only experienced one comet impact that we know of, and it wasn't on earth.

What do all moons have that not all planets have?
craters
How are craters formed on moons or planets?
Craters are formed by impacts from objects from space, such as meteorites.
Why do craters stay on planets and moons?
Many planets and moons have craters because they do not have any significant erosive or geologic forces to destroy them. Most of the craters of Earth have eroded away, been buried under sediment, or destroyed by plate tectonics. Some on Venus likely eroded away or were covered by lava flows. The Planet Mercury and most moons in the solar system do not have these forces to destroy or cover craters.
Does mercury have more craters than the moon?
Which moon? Different planets have different moons. If you are talking about our moon Murcury has more and deeper craters.
Does Neptune's moons have craters?

What are craters named after?
Craters on planets and moons are often named after famous scientists, artists, and explorers. On Earth, some craters are named after geographic features or towns near where they are located.
Does Venus have the most volcanos or craters out of the planets?
Mercury has the most craters of all the planets.
Does the planet mercury have craters or moons?

What are craters on a planet?
Craters are where a chunk of space debris, such as a meteor or comet, has struck the surface of the planet and has caused material from the planets (or moons) surface to be ejected outwards.
Does Mercury have moons craters and mountains?
Mercury has craters and mountains but no moons.
Does the terrestrial planets have more moons than the outer planets?
Oh no, it is the outer planets which have the most moons. Terrestrial planets such as Earth have relatively few moons.
What happens after a craters hits the moon?
Craters don't hit moons. Craters are the results of meteorites hitting moons.
