Solar rotation

Like other celestial bodies, the Sun rotates. This is known as solar rotation. Because the Sun is not solid, the speed of rotation is different in different parts of its atmosphere. At the equator, one rotation takes about 25 days.[1] At the poles, one rotation takes about 38 days. Why this rotation speed varies is currently being researched.[2] The upper and lower chromosphere rotates when the sun rotates.
