"Mesmerising Animation Reveals Our Entire Solar System Doesn't Exactly Orbit The Sun"
This is the headline in the following, admittedly pedantic link:

Here's one of the relatively common diagram's of the solar system's ever-changing barycenter, this one for the years 2000 through 2050...

https://upload.wikimedia.org/wikipedia/commons/archive/b/ba/20200108114154%21Solar_System_Barycenter_2000-2050.png

Note that curve is moving towards a maximum distance from the sun in the early 2020's, which reflects Jupiter and Saturn converging on a conjunction now (so their combined mass is pulling the barycenter away from the sun). That repeats about 20 years from now on the opposite side of the sun. See this earlier topic for a calculation of the nominal 20-year span between Jupiter and Saturn conjunctions...
