In Order of Size, What Position is the Moon In?

Question posed by Mary.

When looking at the Solar System as a whole, our Moon comes in at number 14 based on mean radius, nuzzled in between Jupiter's moons Io and Europa (13^th & 15^th respectively), and appears higher up the table than the dwarf planets Eris (17^th), Pluto (18^th), Makemake (23^rd), Haumea (25^th) and Ceres (33^rd). Our Moon appears only three places below the planet Mercury (11^th) on this list. You can see the whole list here.

If we look at just the known moons of our solar system, Earth's Moon fares rather better, coming in at 5^th place, behind Ganymede, Titan, Callisto and Io (in order, largest first).

Here's a great graphic comparing the sizes of a good portion of our solar system's terrestrial bodies:
