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 the Sun has a huge influence on Earth, many early cultures saw the Sun as a deity or god. For example, in Aztec mythology there is a sun god which is named Tonatiuh. Whilst with the Ancient Egyptians, they had a sun god called Ra.
  6. A person weighing 150 pounds on Earth would weigh 4200 pounds on the sun due to the sun’s gravity
  7. All planets orbit the sun in the same direction, counterclockwise, and on roughly the same plane, known as the ecliptic
  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, it wasn’t until Newton formulated the laws of motion, that Copernicus’s view of the solar system was accepted.
  9. If you happened to live on the Sun and decided to build a spacecraft, it would need to somehow 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
