The Sun (Ahh It's Hot)j

The Sun is a huge, glowing ball at the center of our solar system. The sun provides light, heat, and other energy to Earth. The sun is made up entirely of gas. Most of it is a type of gas that is sensitive to magnetism. This sensitivity makes this type of gas so special that scientists sometimes give it a special name called  plasma. Nine planets and their moons, tens of thousands of asteroids, and trillions of comets revolve around the sun. The sun and all these objects are in the solar system. Earth travels around the sun at an average distance of about 92,960,000 miles from it. The sun's radius  is about 432,000 miles  that's 109 times Earth's radius.

The part of the sun that we see has a temperature of about 5500 degrees C (10,000 degrees F). Astronomers measure star temperatures in a metric unit called the Kelvin. One Kelvin equals  1 Celsius degree (1.8 Fahrenheit degree), but the Kelvin and Celsius scales begin at different points. The Kelvin scale starts at absolute zero, which is -273.15 degrees C (- 459.67 degrees F). Thus, the temperature of the solar surface is about 5800 K. Temperatures in the sun's core reach over 15 million Kelvin.
