Explanations
The Sun is a star with a diameter of about 1.4 million kilometres and a surface temperature of nearly 5,800 Kelvin. With a luminosity of 3.828 × 10²⁶ Watts, it radiates enormous amounts of energy into space. Compared to Earth, the Sun is not only much larger but also the gravitationally dominant body of our entire solar system.
