This is impossible to know, although some may know how to make an educated guess. We don't know the precise number of stars in the Milky Way galaxy, and we are just now learning how to locate planets orbiting relatively close stars. So far, the planets we have discovered are very large and Jupiter-like. This is not because that is the only kind of planet there is outside of our own system; it's because the very large and relatively near-by planets are the only ones we can currently detect. It may be thousands of years before we have a decent idea how many moons there are in our galaxy. We may never know.
