Introduction to The Sun

Ngebray.com,-When you look up at the sky on a clear, dark night, you can see thousands of stars. When you look up at the sky during the day, the biggest, brightest object you will see is also a star. It is our sun. It is the closest star to the Earth.

The sun is the reason life can exist on Earth. It gives us heat, light and energy. Without the sun our planet would be a ball of ice, frozen to the core. The sun also holds our solar system together, because it creates the gravity that keeps Earth and the other planets spinning around it. Without this gravity, the planets would drift off into space.

  • The sun is 109 times bigger than Earth.
  • The sun’s average surface temperature is 5700 degree of celsius. Earth’s average is only 20 degree of celsius.
  • The sun is 150 million kilometres away from Earth. if you could drive a car from Earth to the sun, it would take you 151 years, at a speed of 112 kilometres per hour.
