KOMPAS.com– Sun is the center solar system and belong to the category of the largest star in the universe. The sun has more energy than any other celestial body in the solar system.
Its large gravitational pull keeps small planets, asteroids, comets and other objects stuck in their orbits around sun.
However, does the Sun also rotate?
In reality, the sun does rotate or rotate but it is moving at a much slower speed than Earth.
However, rotation of the sun Unlike Earth Rotation, or planet rotationother planets in this solar system.

If the planet Earth takes 24 hours to make a full rotation, then it is different from the sun.
Because the sun is not a solid object like the planets, its rotation is more difficult to determine.
According to the National Space Agency of the United States (NASA), this is because the sun is a ball of gas or plasma so it doesn’t have to rotate as rigidly as the solid planets and moons
In fact, our solar gas is divided into distinct zones and layers, with each region of our parent star moving at different speeds.
Reported Live Science, Friday (3/6/2016) the rotation of the sun, or the average star rotates on its axis, is once every 27 days.

The equator rotates the fastest and takes about 24 days to turn while the poles take more than 30 days.
NASA further revealed that the inside of the sun also rotates faster than the outer layer.
The Center for Solar Power at Stanford University, England said in 1612 Galileo Galilei saw something strange, namely sunspots moves across the solar disk from time to time and this confirms the rotation of the sun.
Even today, researchers can monitor the movement and rate of rotation of the sun by observing sunspot activity.

Sunspots occurs when solar plasma interacts with its magnetic field and can cause solar flares and other types of solar storms.
Uniquely, these sunspots are cold areas of the sun’s surface, although “cold” is a relative term.
Sunspots average around 5,000 to 7,500 degrees Fahrenheit (2,760 to 4150 degrees Celsius).
This is in contrast to the area around the Sun, which averages around 9,900 degrees F (5,480 C).
