<P> Solar rotation varies with latitude because the Sun is composed of a gaseous plasma . The rate of rotation is observed to be fastest at the equator ( latitude φ = 0 ° ) , and to decrease as latitude increases . The solar rotation period is 24.47 days at the equator and almost 38 days at the poles . The differential rotation rate is usually described by the equation : </P>
