How long does it take the Sun to complete one full rotation on its axis?
It takes the Sun approximately 27 Earth days to complete one full rotation on its axis. However, this isn’t a uniform rotation like a solid planet. Because the Sun is a ball of plasma (hot, ionized gas), different parts of it rotate at different speeds. This phenomenon is known as differential rotation.
The Sun’s equator rotates faster than its polar regions. At the equator, one rotation takes about 24 to 25 Earth days. As you move towards the poles, the rotation slows down significantly, taking as long as 35 Earth days at the polar latitudes. This differential rotation plays a crucial role in the Sun’s magnetic activity and the generation of the solar cycle.
