While the Moon is heavily cratered due to its lack of atmosphere, craters exist on many other celestial bodies, including:

* Planets: Earth, Mars, Venus, Mercury, Jupiter's moons (like Ganymede and Callisto), Saturn's moons (like Titan and Rhea)

* Moons: Many other moons in our solar system besides our own.

* Asteroids: These rocky bodies are often heavily cratered.

* Comets: Though they are icy and less solid, comets can still show impact craters.

So, craters are not unique to the Moon! They are a common feature of many celestial bodies in our solar system and beyond.
