    Lucky for you, the earth and the moon can be treated as point masses in this instance (a point whose size is negligible when compared with its' mass). The center of gravity would be found by creating a diagram of the points (in this case a straight line, the end points being earth, and the moon), and finding the average location of mass, which would be closer to the earth (as it is more massive). The system can be viewed as a large lever system, with the earth on one end, and the moon on the other. The point where they are perfectly balanced would be the centroid.
