3. The sun is about 863,700 miles wide. It is about 110 times wider than the Earth.
4. The sun is the center of our solar system which is located on the edge of a spiral arm called Orion's Arm, and is one-half to two-thirds of the way (28,000 light-years) from the center of our Milky Way galaxy.
5. The sun is mostly hydrogen with about 10% being helium and other elements.
6. The core of the sun is thought to be 27 million degrees Fahrenheit.
7. The sun's light takes a mere 8 minutes to reach earth.
8. If the sun stopped shining all human, animal, and plant life would freeze to death, the tropics would be as cold as the poles, and the seven seas would turn to solid ice.
9. There are 100 billion stars in our galaxy. Six thousand of these stars can be seen with the naked eye from the Earth. The sun is one of these stars.
10. In producing its energy, the sun uses up about 22 quadrillion tons of hydrogen every year. Despite this, according to scientific predictions, the sun contains enough hydrogen to continue shining at its present strength for another 5 billion years.
