Sun

The Sun is a nearly perfect ball of hot plasma, a luminous star at the center of our solar system. It is primarily composed of hydrogen (about 74% of its mass) and helium (about 24%), with trace amounts of heavier elements. The Sun is about 4.6 billion years old and is classified as a G-type main-sequence star (G dwarf). The Sun plays a crucial role in the solar system, providing the light and warmth necessary for life on Earth.
