The planet in my current project is orbited by two moons, which like Mars' are relatively small and irregularly shaped. The largest moon orbits closer to the planet and the smaller one orbits farther away. My question is, which is faster? I know the closer one should orbit the fastest, but since it's larger, I imagine that would slow it down. My current understanding is that the smaller, farther moon would orbit slightly faster, would that be accurate scientifically?
For the sake of simplicity we can say that the second moon is half the size of the first one and the second moon is exactly as far from the first moon as the first moon is from the planet. If it's at all relevant, I also imagine that this planet is smaller than Earth and orbits its star slightly slower and closer than Earth does.
