Dust Release has show the ability to completely obliterate ninjutsu and actual matter. The Truth-Seeking Ball is stated to turn objects to dust just like the Dust Release. In short, it can work on anything that is not Senjutsu; It works on more than just Ninjutsu. I don't know who told you it only works on Ninjutsu (chakra-based constructs) but they were wrong. The Manga proves my point.

With that being said, it wouldn't matter how dense the moon is or if it were solid or hollow, it could still slice through a planetary body without resistance.
