Here's why:
* Center of Mass: Both the Earth and Moon orbit around their common center of mass, called the barycenter. Since the Earth is much more massive than the Moon, the barycenter lies within the Earth, but not at its center.
* Perspective: From our perspective on Earth, it appears as if the Moon is orbiting us. However, the Earth is actually slightly "wobbling" due to the Moon's gravitational pull as they both orbit the barycenter.
So, while it might seem counterintuitive, it's more accurate to say that both the Earth and Moon orbit each other around a common center of mass.
