KOMPAS.com– Sun is the center solar system and is included in 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 traps small planets, asteroids, comets and other objects in their orbits sun.
However, does the Sun also rotate?
In reality, the sun does rotate or rotate but 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 planet Earth takes 24 hours to make a full rotation, then it is different from the Sun.
Since the sun is not a solid object like planets, its rotation is more difficult to determine.
According to the United States National Space Agency (NASA), this is because the sun is a ball of gas or plasma so it doesn’t have to rotate as strongly as the planets and solid moons.
In fact, our solar gas is divided into distinct zones and layers, with each region of our host star moving at a different rate.
Reported Live Science, Friday (3/6/2016), the rotation of the sun or the average star rotates on its axis once every 27 days.

weather systems near Earth. This phenomenon can affect spacecraft and astronauts. NASA has selected five new mission concept studies for further development to study various aspects of this dynamic system.
The sun sends out a constant flow of particles and energy, which drives the complex extraterrestrialThe equator rotates the fastest and takes about 24 days to turn while the poles take more than 30 days.
Furthermore, NASA revealed that the inside of the sun also rotates faster than the outer layer.
The Solar Power Center at Stanford University, England says in 1612 Galileo Galilei saw something strange, namely sunspots moving 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 the term “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 9,900 degrees F (5,480 C).
