The planets don’t orbit the Sun, exactly.

The Sun is “not” a stationary object. It orbits something called the Barry center (the solar system’s center of mass). The path that the Sun takes around the Barry center is highly irregular. The short video below simulates what the changing configuration of planetary orbits would have looked like as they orbited the Barry center from 1960 to 2021 (60-years). In this illustration, the solar system’s center-of-mass (or Barry center) is stationary at the center of the red cross hairs (which is at the center of the red circle). The positions of the planets’, as well as the Sun, are automatically adjusted to show their relative position (distance and direction) to the Barry center (and to each other).
