Moon

A moon is a satellite of a planet that has not been made by a civilization. Moons are a very vague category, and they should arguably be split in two categories: major moons and minor moons. Major moons like our local moon are similar to terrestrial planets but are sometimes a bit smaller. Minor moons are nearly identical to asteroids and are much more common than major moon. Our local major moon orbiting Earth is confusingly called "The Moon", but for redirect sake, we refer to it as Luna on SU Wiki.
