How long does it take the Sun to complete one full rotation on its axis? Correct
The Sun takes approximately 27 days to complete one full rotation on its axis. This period is known as the “sidereal rotation period” of the Sun. The Sun’s equator rotates at a faster rate compared to its poles, leading to this differential rotation across its surface. This rotational period of about 27 days is an average value, as different latitudes on the Sun have slightly varying rotation periods. Therefore, out of the options provided, the closest answer to the Sun’s actual rotation period is 27 days.
