$SOL Sol, the Latin name for the Sun, is the center of our solar system and the primary source of energy for life on Earth. A massive, glowing sphere of hot plasma, it is composed mainly of hydrogen and helium. Through nuclear fusion, the Sun converts hydrogen into helium, releasing immense energy in the form of light and heat.

With a diameter of about 1.39 million kilometers, Sol accounts for over 99% of the solar system’s mass. It has been burning for approximately 4.6 billion years and is expected to last another 5 billion before evolving into a red giant and eventually a white dwarf.

The Sun’s influence extends far beyond providing daylight—it drives Earth's climate, weather, and ocean currents while also affecting space weather, causing solar storms that impact satellites and power grids. Despite its vital role, staring directly at it without protection can cause serious eye damage.
