How long does it take the Sun to complete one full rotation on its axis? Answer
It takes the Sun approximately 27 Earth days to complete one full rotation on its axis. However, this is an average, as the Sun doesn’t rotate uniformly like a solid body. Being a giant ball of plasma, different latitudes on the Sun rotate at different speeds, a phenomenon known as differential rotation.
The Sun’s equator spins the fastest, completing a rotation in about 24 to 25 Earth days. As you move towards the poles, the rotation gradually slows down, taking around 35 Earth days at the polar regions. This variation in rotational speed is a key factor in the Sun’s magnetic activity, which drives the approximately 11-year solar cycle and phenomena like sunspots and solar flares.
