The synodic period is longer because the Sun must rotate for a sidereal period plus an extra amount due to the orbital motion of Earth around the Sun. Note that astrophysical literature does not typically use the equatorial rotation period, but instead often uses the definition of a Carrington rotation: a synodic rotation period of 27.2753 days or a sidereal period of 25.38 days.

The discovery that the sun rotates dates back to the time of Galileo Galilei, according to The British Library. Along with several of his contemporary earlier astronomers, Galileo had observed dark spots of the sun that we now call sunspotsand understand to be important parts of the solar cycle. Galileo noticed something else too. He found these da...
While Earth and the other inner planets are composed of solid rock, the sun is an ultra-hot ball of dense ionized gas — mainly hydrogen and helium— called plasma. That means that the way it rotates is different than the way our planet, Mars, Venus, and Mercurydo. The sun experiences something called differential rotation. This means that its rotati...
The sun's counterclockwise rotation and the counterclockwise rotation of the entire solar system (except two planets) is a result of its formation around 4.5 billion years ago. At this point in the universe's history, the solar system was no more than a giant rotating disc of gas and dust. NASA Science suggeststhat an exploding star caused this to ...

Jun 3, 2016 · On average, the sun rotates on its axis once every 27 days. However, its equator spins the fastest and takes about 24 days to rotate, while the poles take more than 30 days. The inner parts of the ...
Nov 7, 2019 · The gasses and plasma near the sun’s equator rotate around the sun’s axis every 25 days. As you move towards the sun’s poles, the rotation speed slows. Near the north and south poles, the sun rotates once every 36 days. That means the sun’s poles take 11 more days to rotate around the sun’s axis than its equator.
Its spin has a tilt of 7.25 degrees with respect to the plane of the planets’ orbits. Since the Sun is not solid, different parts rotate at different rates. At the equator, the Sun spins around once about every 25 Earth days, but at its poles, the Sun rotates once on its axis every 36 Earth days.
Mar 13, 2012 · A spot on the equator of the Sun takes 24.47 days to rotate around the Sun and return to the same position. Astronomers call this sidereal rotation period, which is different from the synodic ...

Jun 9, 2023 · The mostly gaseous sun "is not a solid body, so it doesn't rotate as a single solid ball," Raftery says. "Instead, the gas rotates more rapidly at the equator than at the poles." A spot at the equator goes around in about 24 days, while the polar regions take six days longer, according to this article on solar rotation on NASA's website.
