I mean this does have a practical application, I think. The relative masses of moons to planets does imply the moons ability to sweep junk out of the way before it hits the planet.

This is not based on mass but on volume. For example the moon is only 1% of the earth’s mass yet considerably less dense therefore it makes a large layer.

Sure. By even the density/mechanical properites of armor will affect its usefulness. Beyond simple thickness.
