what is the sun's orbital period around the solar system's center of mass? is it 24.5 days?

>The Sun, along with our entire solar system, orbits around the center of the Milky Way galaxy at an average velocity of 828,000 km/hr. It takes about 230 million Earth years to complete one complete orbit around the Milky Way.0 The Milky Way also moves, and we are moving towards our nearest neighbor, the Andromeda galaxy, and both the Milky Way and Andromeda are moving towards the Virgo Cluster, which is our nearest cluster of galaxies.1 The Sun moves slowly and takes 25 days (equator) and 35 days (poles) for the Sun to complete one full revolution.2

Jupiter is far more massive than all other solar system bodies orbiting the Sun combined. Thus the barycentre of the solar system must be close to the barycentre of the Sun and Jupiter, which lies between the two bodies slightly outside the Sun's surface. This would mean that the Sun's orbital period around this barycentre is equal to the orbital period of jupiter, which is around 12 years

so the sun doesn't rotate in 24 days, it orbits the solar system's center of mass in 24 days, so presumably the center of the sun rotates faster than the exterior

That is the center of mass of the solar system. If you think that there is some gravitational center of mass distinct from a regular one, you are likely mistaken.

The time it takes for the Sun to complete one full orbit around the solar system barycenter is approximately one year. This period is the same as the Earth's orbital period around the Sun because the Earth is the most massive object in the solar system after the Sun. As a result, the barycenter is often located within the Sun, but it can be offset due to the influence of the other planets, especially massive ones like Jupiter.

~19.86 years on average, but with quite a bit of variation
here's a plot I generated of the barycentric motion over a few thousand years
as you can see there's a period of ~179 years, corresponding to 9 rotations, after which the general motion repeats, except with certain variations in parts of it

none of that's wrong, that's all objectively true and well-measured
the orbital period of Sol around the barycenter of the Solar system is absolutely nowhere close to its rotational period
the orbital period is, as shown clearly above, ~19.86 years on average, but with some variation, whereas the rotational period of Sol is as little as ~25 days at the equator and as much as ~38 days near the poles (differential rotation), i.e. not even remotely as long as the orbital period

again, blatantly false, and totally incorrect reasoning, because distance and orbital period are only inversely proportional for simplified 2-body systems where one mass (that of the star in the cases we're interested in) is dominant
it does NOT apply to the Solar barycentric motion itself
