Here’s your chance to slap your know-it-all friends in the face with some knowledge. Every object exerts force on every other object, which means that not only does the sun’s gravity affect Earth’s motion, but Earth’s gravity affects the sun’s motion. Technically, both objects orbit around something called the barycenter. For Earth, this point is so close to the core of the sun that it doesn’t make much of a difference. For Jupiter, however, the barycenter is roughly 30,000 miles away from the surface of the sun. So in some sense, we’re all orbiting around each other.
