Does the sun rotate - and does it make any difference?
- JackolanternLv 73 months ago
At it's equator, a full rotation is around one earth month. The rest of the sun rotates much slower as you get from the equator and closer to it's poles. This makes a big difference because this shearing motion causes magnetic fluxing and huge solar storms on it's surface.

Sun acts as a giant solenoid

Yes, the sun rotates. On average, the sun rotates on its axis once every 27 days. However, its equator spins the fastest and takes about 24 days to rotate, while the poles take more than 30 days. The inner parts of the sun also spin faster than the outer layers, according to NASA.

All ACTIVE and LIVE planets and stars rotates - if they stop rotating then they may cease to exist soon !

Yes, it rotates and if it didn't rotate there would be no 22-year magnetic cycle which could affect weather on Earth.

Yes, it rotates, and not as a "solid body" --- it's a shorter period at the equator than closer to the poles. That differential rotation drives the "dynamo" that generates the Sun's magnetic field and ultimately drives the Solar Wind.
The Solar Wind and the Sun's magnetic field help shield us from the highest energy cosmic rays in interstellar space, and they keep interstellar dust out of the Solar System.

If the sun do not rotate then how all the planets of the Solar System revolve around the Sun then. The Sun rotate in anti clockwise direction, then all the planets revolve around the sun in anti clockwise direction too. Moreover the Solar System revolve around the axis of Milky way galaxy too.

Yes, and it makes a difference--
The progress of features like sunspots, flares, and loops in the atmosphere above the surface can be seen marching across the face we see.
The sun's magnetic field loops become entangled because of the differential rotation rates of equator, middle zones, and poles. These lead to major activity of the sun and sometimes, massive discharges of matter from the sun. This could effect weather on earth, satellite and manned mission survivability, and even the use of electricity all over the Earth. So that seems to be really important to humans.

Being Plasma, the Sun's Equator Spins faster at its Equator than at its Poles
At a Diameter of about 1.3 Million Miles, its Diurnal time is 26 days
A Surface Velocity of about 33, 000 mph

It does rotate, but it's not a solid mass, so the equator actually rotates faster than the areas toward the poles.
The equator of the sun rotates in about 28 days, while it's up to 34 days to complete a rotation closer to the poles.
