Yes and no. Many of them are covered with impact craters like our Moon, but the moons of Saturn are made up of much more water ice than Earth’s moon. Earth’s Moon may have very tiny patches of ice, but almost all its mass is rock. Because of this, most of Saturn’s moons are about one-third the density of our Moon. Titan’s density is a little higher, but still only about half as dense as Earth’s Moon. Saturn’s outermost moon, Phoebe, may be a captured asteroid, in which case it would likely have a much higher density. Titan is the only one of Saturn’s moons that is larger and more massive than our Moon. All the rest are significantly smaller and less massive, and many of them are irregularly shaped rather than spherical. Also, unlike our Moon, and un-like all of the other 60 or so moons in the Solar System, Titan has a thick atmosphere.
