It's not technically the sun. It's the center of mass of both the Earth and the Sun. However, since the sun is six orders of magnitude more massive than the Earth, the technical differences are negligible, and the counter-orbit for the sun is only 280 km. The only two planets that do have a significant counter-orbit apparently are Jupiter and Saturn, and for both of them the center of mass is well within the sun's radius.
