Does the Sun rotate like the Earth?

Jeff Kish asked the Naked Scientists:

Does the Sun rotate just like the Earth?

What do you think?

The sun's rotation is more like Jupiter's: the surface is gaseous and the equator rotates faster than the poles.

Yes, the Sun is spinning on its own axis, but because the Sun is effectively a fluid rather than a solid (like Earth) the movement of that fluid, as RD suggests, is not uniform across the Sun's surface. The equator rotates about every 5 days whilst the poles rotate about every 30 days.

We have interviewed Chris Davis, from the Rutherford Appleton Laboratory, about his astrophysics research on a couple of occasions:

With the Earth having so much surface water, would the same principles of fluid dynamics not apply to some extent?
