Small Moon

Small moons are so small that they are hard to see! The pictures we have of these moons are often fuzzy. This makes it hard to know anything specific about the moons. Small moons are about the size of a city.

Picutres of small moons will get better as our cameras sent into space get better. Here's an example of a picture of Saturn's moon Helene.

Most small moons seem to be made of ice, for example Uranus' moon Miranda.
