3. At the Sun’s core, energy is generated by nuclear fusion, as Hydrogen converts to Helium. Because hot objects generally expand, the Sun would explode like a giant bomb if it weren’t for its enormous gravitational force. The temperature on the surface of the Sun is closer to 5,600 degrees Celsius. The temperature of its core is about 15 million degree celsius.

7. Like Earth Sun also revolves around the galaxy. It takes 224.7 million years to complete an year otherwise known as cosmic year.

8. Every day, plants convertsunlight into energyequivalent to six times theentire power consumptionof human civilization.

9.All of the world’s energy needs can be met with 1/10,000th of the light from the Sunthat falls on Earth each day, according to the inventor Ray Kurzweil.

10.A bolt of lightning is 5 times hotterthan the surface of the sun.

14. The sun is the most perfectly roundnatural object known in the universe.

15. The core of the Sun has a temperature of about15,000,000 ° C(27,000,000° F).

16. In 1666, Isaac Newton observed the Sun’s light using a prism, and showed it is made up of light of many colors.

17.The American flagsplaced on the moon are now white due toradiation from the sun.

18.The Earth’s coreis about as hot as the sun.

19.Partial solar eclipses are hazardous to view because the eye’s pupil is not adapted to the unusually high visual contrast.
