Small Moon

A small moon is a moon which is hard to see. The pictures of these moons often have poor resolution. In general, no detailed spectra of these moons have been taken. This makes it hard to know anything specific about these moons. Small moons are about the size of a city.

As the cameras we send into space aboard spacecraft improve so will the pictures we take of these small moons. An example of a small moon is Saturn's moon Helene which is only 10 miles across! It is still difficult to say anything about this moon because the features are too hard to see.

Most small moons are also icy, meaning that they seem to be composed of ice. For example Uranus' moon Miranda which is small, only 200 miles across, but seems to be made of ice. Some small moons may be rocky, however.
