Differential Rotation means that different parts of the Sun rotate at different speeds.

* Equator: The Sun's equator rotates fastest, completing a full rotation in about 25 days.

* Poles: The Sun's poles rotate much slower, taking about 36 days to complete a full rotation.

This difference in rotation speed is due to the Sun's internal structure and the nature of its plasma. The Sun is not a solid body, but a ball of hot gas. The gas at the equator is less dense and experiences less friction, allowing it to rotate faster. The poles, on the other hand, experience more friction and rotate slower.

This differential rotation has significant implications for the Sun's magnetic field and activity, including the generation of sunspots, solar flares, and coronal mass ejections.
