Compared to Earth’s rotation, that huge blazing star in the sky rotates. The Earth takes 24 hours to complete a full rotation, but the sun’s rotation is more difficult to measure because it is not a solid object like a planet.

According to NASA, it doesn’t have to rotate like the solid planets and moons because the sun is a gas/plasma ball.

Our host star’s gaseous sun is divided into zones and layers that move at different speeds. The sun revolves around its axis on average every 27 days. However, its equator spins the fastest and takes about 24 days to complete a rotation, while the poles take more than 30 days to complete. According to NASA, the sun’s inner layers spin faster than its outer layers.

Stanford University’s Solar Center reports that in 1612, astronomer Galileo Galilei noticed a strange phenomenon: as he watched the sunspots move across its disk over time, he concluded that the sun rotated. Researchers can still keep tabs on the sun’s movements and rotational rate by keeping an eye on its sunspot activity.

As a result of the plasma-magnet field interaction in sunspot regions, solar flares and other types of solar storms are possible outcomes.

Generally, sunspots should be hot, but they’re cold areas on the sun’s surface. There are a few places on the sun’s surface where temperatures can reach up to 7,500 degrees Fahrenheit (2,760 degrees Celsius), but most of the rest of the sun’s surface is cooler.
