Facts About The Sun For Kids | The Brightest Star

The first thing you should know about the Sun is that it is not a planet but a star. A spherical-shaped star is actually made up of burning plasma interconnected with magnetic fields. There was a time when astronomers thought it as an undersized star with little or no significance. But not anymore because today scientists believe the Sun is more dazzling than almost 85 percent of all the stars in our galaxy. The sunlight is extremely important to keep the natural life in our planet alive through the process of photosynthesis. Not only this, the energy from the Sun also changes the meteorological conditions of the Earth. Hence the Sun is a bright star with lots of elements. Aren’t they one of the enthralling facts about the Sun for kids? If yes, then just don’t break off here because we’re going to have a thrilling journey to explore some of the wonderful facts about the Sun for kids.

Some Of The Amazing Facts About The Sun For Kids

  • Sun is present at the focal point of our solar system.
  • The size of the Sun is about 109 times bigger than our planet (Earth).
  • About 99.86 percent of the mass of our solar system is present inside the Sun.
  • Almost three-quarters of the mass of Sun are comprised of Hydrogen whereas the remaining consists of Helium.
  • Sun was created way back 4.6 billion years before.
  • After every second, Sun merges 620 million metric tons of Hydrogen inside the core.

  • Sun is the most luminous star, which is probably nearest to our planet than any other star.
  • The Sun is at the fourth position in terms of its mass among the fifty stellar systems that are closest to the Earth.
  • The orbital movement of Sun around the focal point of the Milky Way is occurred within the expanse of almost 24,000 to 26,000 light years from Galactic Center.
  • The average distance between the Earth and the Sun is nearly 149.6 million kilometers.
  • The light passes from the Sun to our planet within just eight minutes and nineteen seconds.
  • Because of the fact that Sun is made up of plasma instead of solid substance, so the orbital movement of the Sun at the equator (25.6 days) is relatively quicker as compare to the movement at the poles (33.5 days).
  • Unlike the rocky planets of our solar system, Sun has no specific border. Instead at the most exterior sections of the Sun, the thickness of gases falls as the span from the central point increases.
  • The temperature at the core of the Sun is about 15.7 million Kelvin. It is far more than the temperature at the surface which is 5,800 Kelvin.
  • There is no other section of the Sun that yield substantial amount of thermal energy except the core of the Sun.
  • The enormous output force of the Sun is only because of its colossal size and not because of the great power per volume.
  • The obvious Sun’s surface is a layer which is known as photosphere and underneath this layer the Sun’s energy cannot be disseminated to the outer space.
  • The inner region of photosphere is hotter than the outer surface.
  • The coldest temperature at almost five hundred kilometers over the photosphere is 4,100 Kelvin.
  • The exterior of the Sun’s atmosphere is much bigger in size as compare to the size of the Sun itself.
  • The mass of the Sun is not sufficient to blast like a supernova.
  • The temperature at the photosphere is about 6,000 Kelvin.
  • The brightness of the Sun at about 3.8 billion years before was just seventy five percent.
  • If you stare directly at the sunlight for an extended period of time, the effect can be dangerous and also bring about phosphene visual artifacts along with short-term loss of sight.
