The Sun


The sun, the star at the center of our solar system, controls everything within its mighty gravity field, commanding planets to orbit or pulling comets straight into it. It holds 99.8 percent of the solar system's mass, and measures roughly 109 times the diameter of the Earth. The visible part of the sun reaches a temperature of roughly 10,000 degrees F (5,500 degrees C), while temperatures in the core exceed 27 million degrees F (15 million degrees C), driven by nuclear reactions. It's plenty dangerous!
