Does the SUN have an Orbit ?

[New Age; New Times; New Ideas]

To the leaned/known ?

This question may cause me more mail than its worth but I'm going to
ask it .
I read in a book only two days ago that the SUN (yes the center of
our solar system) may also revolve around in an orbit path.
This could be quite possible in the fact that, if you have a heap of
planets swinging off a central point namely the SUN could they not
pull/push the SUN around a small orbit also. If this is such
that means there may be another actual center of our solar system ?
Could that center be magnetic,blackhole,antimatter or something to that nature.
I don't wish to stirr up a can of worms as I have only a limited knowledge
of the wonderous univers ,but the question is bugging me.

Any comments (no doubt I will recieve ) welcome.

The above theroy is not my own, I wish only to ask if this is possible.

Probably they mean that the sun is in orbit around the galactic centre.

The sun _does_ orbit, not only about the galactic center, but about the
center of mass (c.o.m.) of the solar system, which I believe is beneath
the surface of the sun. Jupiter being the second most massive body in
the solar system, it moves the c.o.m. of the solar system a bit away
from the center of the sun, so that effectively (discounting all the
other planets) the sun and jupiter move in elliptical orbits with the
same period around the c.o.m. of the two of them.

I calculate that it's just above the "surface" of the Sun. The Sun has a
mass of about 1050 Jupiter masses, and Jupiter is about 1120 Solar radii
from the Sun. So the center of mass is, by coincidence, quite close to
the outer atmosphere of the Sun.

Yes, and no. The Sun and the planets circle around the center of mass
of the Solar System. However, the center of mass is inside the Sun,
fairly close to, but not quite at the center of the Sun, so it makes more
sense to consider the Sun as fixed, and not rotating. This is in
addition to the Solar Sytem's (and, thus, the Sun's) rotation around the
center of the Milky Way.
