10 Facts About the Sun

Here are some interesting facts about the sun:

  1. the sunWith a total width of around 865,000 miles (1,392,000 kilometres), the Sun’s diameter is about 110 times wider than the Earth’s
  2. It takes around 8 minutes for the Sun’s light to reach Earth
  3. Due to the speed at which the sun moves, it’s impossible for a solar eclipse to last any longer than 7 minutes and 58 seconds
  4. Approximately 109 planet Earths would fit on the surface of the sun and more than one million planet Earths would fit inside it
  5. Because of the Sun’s huge influence on Earth, many early cultures saw the Sun as a deity or god. For example, Ancient Egyptians had a sun god called Ra while in Aztec mythology there is a sun god named Tonatiuh
  6. A person weighing 150 pounds on Earth would weigh 4200 pounds on the sun due to the sun’s gravity

  8. In the sixteenth century, Nicholas Copernicus argued that it was the Earth that traveled around the sun – not the sun traveling around the Earth, as thought for centuries. However, Copernicus’s view of the solar system wasn’t accepted for many years until Newton formulated his laws of motion
  9. If you lived on the Sun, and you built a spacecraft, it would have to go over 384 miles / 618.2 kilometres per second to escape the Sun’s gravitational pull. That’s about 40 times faster than the average passenger plane
  10. Sunlight sustains all life on earth, allowing the plants to produce food through photosynthesis. No sun? Eventually, no life
