  • Star Type
    G2V
  • Date of Discovery
    Unknown
  • Learning Point
  • The sun is the source of heat and light within our Solar System. Both these are produced by the nuclear reactions at the core of the sun, and are then transported out to the surface and into space, eventually reaching us.
  • Project
  • Draw the sun's structure.
  • Location
  • Located in
    Our Solar System
  • Fun Facts
  • The sun's core is where the fusion of hydrogen atoms occurs, causing energy that is the source of heat and light.
  • It takes more than a 100,000 years for the energy from one atom to reach the surface of the sun.
  • The sun has a radiative zone outside the core that moves the heat outwards in one direction.
  • The outer section of the sun is the convection zone which is where the heat and energy is transferred up in a cycle, so it moves upwards and downards in a circular motion.
