Technically, Earth Does Not Orbit Around the Sun (2014)

“Technically, what is going on is that the Earth, Sun and all the planets are orbiting around the center of mass of the solar system,” writes Cathy Jordan, a Cornell University Ask an Astronomer contributor. “The center of mass of our solar system very close to the Sun itself, but not exactly at the Sun’s center.” The solar system is basically a massive game of tug of war, and all of the yanking balances out at a specific point: the center of mass, or “barycenter.”
