The Sun
Star of the Solar System
The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. It radiates this energy mainly as light, ultraviolet, and infrared radiation, providing the energy for life on Earth.
- Diameter: 1.4 million km
- Surface Temp: 5,500 °C
- Mass: 333,000 Earths
Scale of our star
A blazing, turbulent Sun dominates the scene as a vast sphere of incandescent plasma, its surface alive with swirling magnetic currents and eruptive flares that radiate immense heat and light. Arrayed below it, the planets appear tiny by comparison, emphasizing the staggering scale of our star—a fusion-powered engine that governs the solar system with its gravity.
