What Is Solar Energy?
The Sun is a star, the center of our solar system (so-lar sys-tem). The Sun appears larger than other stars because it is closest to Earth. The distance between Earth and the Sun is about 150 million kilometers.
Like other stars, the Sun is made of boiling gases called hydrogen (hy-dro-gen) and helium (he-li-um). The gases are so hot, they make the Sun glow. The temperature at the center of the Sun, or the core, is 27 million degrees Fahrenheit. The Sun's energy or solar energy (so-lar en-er-gy) comes from deep inside its core.
