Well no outer planet has only one moon they all either have more than 1 or none at all.

Yes they do. Our moon only orbits our planet - earth.
The Earth is the only planet in our Solar System with one Moon
The moon is the (only) "natural satellite" of the earth. It is not a planet.
The only planet with one moon is Earth. The smallest planet is Mercury but it doesn't have any moons.
A couple of years ago, I would have said "Pluto" which has one moon - Charon. But Pluto has been demoted to "dwarf planet" or "Trans-Neptunian object", so it seems earth is the only planet with just one moon in our solar system.
Earth is the major planet in our solar system that has only one moon, which is called the Moon.
