Where is Earth's center of mass? The answer seems trivially obvious. It's right in the middle of the planet. Ah, but that kind of thinking won't get you a paper in the Geophysical Journal International. It's also not a trivial question. Knowing Earth's center of mass to within millimeters reveals some interesting facts about our planet.
