Suns are often considered the life-force of our solar system, providing us with light and heat. They have a fascinating history and many secrets that have been revealed over time. Here are 10 fascinating facts about Suns:
1. The surface temperature of a Sun can reach up to 10,000 degrees Fahrenheit – this is hotter than most stars in the universe!
2. A single Sun contains more mass than all the planets in our Solar System combined – this is due to their high density and size.
3. Every second, Suns create enough energy to power Earth’s electricity needs for an entire year – this is thanks to nuclear fusion reactions at their core which convert hydrogen into helium and release huge amounts of energy.
4. The light from a Sun reaches us 8 minutes after it is created – this is due to the speed of light and its vast distance away from Earth.
5. Most Suns in our galaxy are billions of years old – their age can be estimated by measuring their luminosity, size and temperature.
6. Suns emit more than just visible light – they also release ultraviolet radiation which can cause skin cancer if not protected from properly with sunscreen or other methods of protection.
7. Suns are composed mostly of hydrogen and helium – these two gas giants make up around 74% and 24% respectively of a Sun’s mass, leaving only 2% for all other elements combined!
8. Suns can be seen in multiple colors – due to their high temperatures, they appear yellow or white from Earth but also with other hues like blue, green and red when observed from space.
9. Suns emit X-rays which are invisible to the human eye – these penetrate through our atmosphere and can be detected by special telescopes on the ground or in space.
10. Stars live for billions of years before eventually dieing out – this is because they exhaust all the fuel at their core and start to cool down until eventually becoming a black dwarf star!
