Some words that describe the sun are hot, dense, spherical, huge, massive and layered. The sun also can be described as productive because it produces heat, light and radiation.
Heat is one of the defining characteristics of the sun. At its core, nuclear fusion results in temperatures of 27 million degrees Fahrenheit and higher. The sun is both the center of the solar system and the largest member of the solar system. The sun's diameter is 1,390,000 kilometers.
The sun is made up of several layers called the core, photosphere, chromosphere and corona. Solar winds originate in the corona and jut out into space.
