No actually. Due to Jupiter, the centre of mass of the solar system is actually very slightly outside of the sun

Leave it to Jupiter to mess yet another thing up

Stupid lazy ass diabetus planet doesn't even have enough mass to fuse its hydrogen.

Wouldn’t the center of mass constantly be shifting by the planets’ varying positions in orbit?

Yes, but it's mostly shifting because of Jupiter. It's just so dang heavy. Like, a couple times heavier than every other planet put together. I don't have the brain wattage to do the cool math right now, but a quick google search says that while the barycenter of the solar system does depend on all the planets, more often than not, it is outside the sun

Easy reminder:

sun ~ 10^30 kg
jupiter ~ 10^27 kg
earth ~ 10^24 kg

so the ratio is always 1000:1

relative to the center of the Milky Way, yes.

Sadly, the quantum foam has no gridlines.

So doesn't that mean the earth and sun do not orbit a common center but a varying point based on mostly Jupiter?

Centrists have bamboozled me again!

Cool. I learned something today

But I think the math of the argument is only about the common center between Earth and the sun, taking away all other planets out of the equation, especially Jupiter.
