The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convectivemotion that generates a magnetic field via a dynamo process. It is by far 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 that of Earth, accounting for about 99.86% of the total mass of the Solar System. About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.

The size of the Sun compared to the largest known stars (red
giants) is not very big. However, if compared to the most common type of star
in the universe, the red dwarf, the Sun is quite a bit larger. Thus, the Sun is
not the biggest type of star in the universe, but it is definitely larger than
most.
Sun’s mass compared to other bodies found in our solar
system, .The Sun is most massive,The Sun alone contains 99.8% of the total mass in the Solar System.
