It is difficult to throw a baseball, or any kind of ball without any spin. What causes the moon to act like a "knuckleball"?

But other planet's moons rotate with respect to the planets. It's because our Moon is tidally locked with the Earth - it rotates exactly once in it's orbit as it goes around us. Look up 'tidally locked' for more info.

It's the gravitational pull...
Thanks for the laugh, this question just reminded me of that episode of the family guy where Brian told Peter he had his own gravitational pull because he was fat.. And he threw all these objects up and they all spun "knuckleball" style around Peters waist!

In essense we do, the gravitational force the moon exerts on us as it rotates moves us slightly in our orbital path. but since we're the astrological body with greater mass the moon is said to rotate around us.

the moon absolutely does rotate! it just rotates at the same rate earth does (due to gravatational pull) so we only see one side of the moon

Eri is right. Hey Eri, how do you always beat me to these questions?
