There's a bunch of stuff about Earth's moon that makes it fairly unusual in our solar system. Though, 30 years ago the solar system itself was completely unique so far as we knew, so it's likely we'll find other planets with similar satellites.
Of particular interest is the size of the moon relative to earth (about 25% of our diameter), it's density relative to earth, and the current leading theory for the formation of the moon (collision between Proto-Earth and a Mars-sized protoplanet).
