Detailed explanation-1: -Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun’s equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days).
Detailed explanation-2: -The rotation of the Sun is due to conservation of angular moment. What this means is that the gas cloud from which the Sun formed had some residual angular momentum that was passed-on to the Sun when it formed, which gives the Sun the rotation that we observe today.
Detailed explanation-3: -Since the Sun is a gas and not a solid, it rotates differently than any planet. The Sun rotates faster at its equator than at its poles. It rotates once every 24 at its equator. Yet, the Sun only rotates once every 35 days at its poles.
