When studying space in school, you might be asked to compare and contrast the moons that were discussed in a chapter. What they want you to do is to write about the way the moons are all the same and the things they have that make them different from each other.
There is no standard collective noun for 'moons' because moons are usually not in groups. A collective noun is a word used to group people or things in a descriptive way.
The word moon is a singular noun. The plural noun is moons.

Mars' moons are much smaller than, for example, Earth's Moon, or the larger moons of Jupiter. A large moon will have a larger gravity, which will tend to pull the moon together into a spherical shape.
