The Sun takes about 27 days to complete one full rotation on its axis as observed from Earth. However, this rotation period varies depending on the latitude because the Sun is a gaseous plasma and does not rotate like a solid body.

• At the equator, the Sun rotates fastest, completing a rotation in approximately 24 to 25 days (sidereal rotation period is about 24.47 days)

• Near the poles, the rotation is slower, taking more than 30 days, up to about 35-36 days

• The commonly used average rotation period, known as the Carrington rotation, is about 27.3 days, which corresponds roughly to the rotation rate at about 26 degrees latitude, where sunspots typically appear

This differential rotation arises because the Sun is made of plasma rather than solid material, causing different latitudes to rotate at different speeds

. In summary, the Sun completes one full rotation on its axis in roughly 27 days on average, with faster rotation at the equator (~24-25 days) and slower rotation near the poles (~35-36 days)
