Q5         Ifeverything in this solar system is rotating, then why does the Sun 
not rotate?

A5         Tilock Sadhukhan, Subject Matter Expert in Advanced Physicsat Chegg

The Sun does indeed rotate, but itsrevolution is not uniform throughout its 
entire surface due to a phenomenoncalled differential rotation. Let me explain:

 

The Sun is a gigantic ball of heated, ionized gas (plasma) thatconducts a 
process called nuclear fusion at its center, where hydrogen atomsfuse to make 
helium, releasing an immense amount of energy in the process. Thisenergy 
radiates outward, generating the light and heat that sustain life onEarth.

However, the Sun is not a solid body like a planet; it'scomposed of layers of 
gas that rotate at different rates. This is known asdifferential rotation. 

The equator of the Sun rotatesfaster than its poles. Thisis due to the fact 
that the Sun is not a hard entity; its gaseous compositionallows various 
sections to rotate at different speeds.

The solar equator takes roughly 24 days to complete onefull rotation, while at 
the poles, the rotation duration might be around 35days.This phenomenon has 
been proven through observations of sunspots, which areregions of extreme 
magnetic activity on the Sun's surface. By tracking the migrationof sunspots, 
astronomers have estimated the Sun's differential rotation.

In summary, the Sun does rotate, but its revolution is not uniform due tothe 
asymmetrical spinning of its gaseous layers. 

This rotation has a crucial influence on the Sun's magneticactivity, solar 
flares, and other phenomena that affect space weather andconditions on Earth.

My note- I think this QA gives some basicinformation about Sun in the context 
of ISRO launched today Aditya-L1: ISRO's solar mission.
