  Star The sun isa Star made of hydrogen and helium. The sun is located at the center of the solar syste Star is an object that produces it own energy, including heat and light. Astronomical Unit is the closest stars to the solar system are found in the Alpha Centauri star system. The size of the Sun If the Sun were a hollow ball more than a million Earths could fit inside it! The Sun is an average size star and the largest object in the solar system. The Sun looks larger than the other stars that can be seen in the night sky because it is much closer to Earth. What are the Parts of the Sun? The Sun is a huge sphere made up of mostly of two gases. 71% of the Sun’s mass is Hydrogen 27% of the Sun’s mass is Helium The remaining 2% is Oxygen and Carbon Parts of the Sun!

  The Core Most ofthe energy that the Sun produces is formed in it’s core. The Core’s temperature is 10 million to 20 million degrees Celsius. The pressure is more than 1 billion times greater than the air pressure of Earth. Radiation Layer Next to the core Moves the energy produced in the core in every direction. It can take million of years for energy to move out of this layer. Convection Layer next to the radiation layer. Gasses with different energies move in circles in a way similar to air with different densities. Energy moves out of this layer in about a week. Photosphere Is the visible surface of the sun. It is not a solid surface, but rather a layer of gasses. It is cooler then the core with a temperature of 10,346 F.

  Chromo sphere Is theinner layer of the Sun’s atmosphere? When it can be seen it looks like a red circle around the Sun. The Corona The outermost layer of the Sun’s atmosphere. The corona takes on different shapes around the Sun depending on changes in the temperature of the photosphere. Solar Flares are burst of heat and energy that stretch out from the corona and chromospheres into space. Sometimes the energy disrupts satellites, interfering with TV, radio, and cell phone communication systems.

  Aurora Borealis -also calledthe Northern Lights Energy from the solar flares also causes displays of different-colored lights in the upper atmosphere. Most often seen in Alaska, Canada, and the Northern United States Sun Spots Solar Flares are also sometimes associated with sunspots They are dark spots on the Sun They are regions of the photosphere that have a lower temperature then the surrounding regions. I how do the Sun produce energy? 100 years ago, Albert Einstein discovered a relationship between energy and mass. The E stands for energy, M stands for mass, the C represents the speed of light What happens inside the Sun Hydrogen particles smash together to make helium. This smashing is called Fusion little bit of mass is a lost when hydrogen particles combine to make helium. The mass in turned into energy we see this energy as light and heat!
