Hi Alisha, we haven’t found all the planets in the universe yet so we don’t know how many moons there are. But there must be lots – we have over a hundred moons in just our galaxy, and there’s billions of galaxies in the universe so there’s probably billions of moons!
@alishan I’m with Alex and Alison on this one. It’s very unlikely that we’ll get a answer to this question in our lifetimes, or even in our childrens lifetimes. Isn’t it exciting that there is still so much out there to learn in science!
