The sun forms a very important part of the solar system. It accounts for 98% of the total mass
of the solar system. The sun is not solid like the earth. Instead, it is composed of plasma. As a
result, it rotates faster at its equator than at its poles. It takes almost twenty-five days to
complete its one rotation at the equator and thirty-three days to complete its one rotation at the
poles. The major elements that constitute the sun are hydrogen and helium. It is also composed
of other elements like iron, nickel, oxygen, etc. The visible surface of the sun is called the
photosphere. It heats up to a temperature of about 6000 Kelvin. The core of the sun, however,
has a temperature exceeding thirteen million Kelvin. The sun also has a strong magnetic field
.This is responsible for effects such as sun spots, solar flares, ete. The sun is a life-force for
earth. The light from the sun is essential for all living things. It aids in the process of the
photosynthesis for plants. It also helps in the production of vitamin D. However, the excessive
exposure to sunlight can create serious damage in the form of sunburn, cancer, etc. The sun
has also been an important cultural symbol throughout history. The ancient Egyptian God Ra.

Answer:
The Sun is the star at the centre of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light, ultraviolet light, and infrared radiation. It is by far the most important source of energy for life on Earth.
