If everything in this solar system is rotating, then why does the Sun not rotate?

The Sun does, in fact, rotate, but its rotation is not as straightforward as the rotation of solid objects like planets. The Sun is composed of hot, ionized gas (plasma) rather than a solid surface, which leads to a different kind of rotation called differential rotation.

Differential rotation means that different parts of the Sun rotate at different rates. Near the Sun's equator, it rotates more quickly, taking about 25 to 35 days to complete one rotation. However, as you move toward the poles, the rotation rate decreases, and it takes longer for the Sun to complete a rotation. At the solar poles, it can take around 35 days or more for the Sun to complete a full rotation.

This differential rotation is due to the Sun's gaseous nature. The outer layers of the Sun, particularly the equator, experience more friction and drag from the solar magnetic field, causing them to rotate faster. Deeper layers of the Sun rotate more slowly. This phenomenon is a result of the complex interactions between the Sun's magnetic fields and the convective motions of plasma in its interior.

So, while the Sun does rotate, its rotation is different from that of solid objects like planets, making it a fascinating celestial body with a dynamic and ever-changing behaviour.
