THE SUN & ITS ROTATION YOU NEED TO KNOW — READ IT !

The word ‘sun’ came from Middle English ‘sunne’, from Germanic language ‘sunn’. The Sun is
the star at the center of the Solar system. It is nearly a perfect sphere of hot plasma ( Lightning
and neon lights are common place generators of plasma) with internal connective motion that generates a magnetic field via a dynamo process. It is the most important source of energy for
life on earth. Its diameter is about 1.39 million kilometers,i.e. 109 times that of Earth, and its
mass is about 330,000 times of Earth, accounting for about 99.86% of the total mass of the so-
-lar system. About three quarters of the Sun’s mass consists of hydrogen (73%), the rest is mo-
-stly helium(25%), with much smaller quantities of heavier elements, including oxygen, carbon,
neon and iron. The Sun has been regarded by some cultures as a deity. They say, the source of
all powers is Sun. The surface temperature of the Sun is almost 10,000 degrees Fahrenheit. The
interesting fact is — Sun does rotate. “Since the Sun is a ball of gas/plasma, it does not have to
rotate rigidly like the solid planets and moons do”, according to NASA. In fact, our gaseous Sun
is divided into different zones and layers, with each of our hot star’s regions moving at varying
speeds. 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 to rotate.
The inner parts of the Sun also spin faster than the outer layers, according to NASA. Back in
1612, Galileo Galilei noticed something odd : Sun spots moved across the sun’s disk over time,
confirming the Sun’s rotation, according to Stanford University’s Solar Center. Even today,
researchers are able to monitor the Sun’s movements and rate of rotation by observing its
sunspot activity.
