Sun
The Sun is the star located at the solar system’s center. Its gravity holds the solar system as a whole together. It accounts for about 99.86% of the total solar system’s mass.
Hydrogen is about 73% of the Sun’s total mass; the rest is mostly Helium (25%), with a small quantity of oxygen, carbon, neon, and iron. The hottest part of the Sun is its core, where temperatures top 27 million degrees Fahrenheit (15 million degrees Celsius).
The core is the place where it generates enormous amounts of energy through the nuclear fusion reaction. It mainly radiates energy through visible light, ultraviolet, and infrared radiation.
