 Earthlings, let's discuss some facts about the sun. The Latin word for the sun is soul, and it is used to describe all things sun-related, such as solar eclipse, solstice, solar power, or your solar system. The sun is a 4.5 billion years old yellow dwarf star. It takes around 27 Earth days to complete one full rotation on its axis. About 74% of the sun is made up of hydrogen. And guess what? Helium, the gas that makes balloons blow, fills approximately 24% of the sun. The sun's surface temperature is a mind-blowing 10,000 degrees Fahrenheit. Incredibly, the sunlight reaches you on Earth in just about 8 minutes. That's the speed of light. Take a moment to bask in the sun's radiant glory, but don't forget to use sunscreen to protect yourself from its powerful rays.
