Document Summary
Like the planets the sun is also made up of different layers, though they come about for different reasons. At the core, fusion is the source of energy for the sun. Our sun is a smaller cooler star. It has an intrinsic brightness of 4. 83 on the magentide scale - how much brightness the star lets out. The sun and most other stars are made up of about 90% hydrogen atoms and about. 10% helium atoms, with small traces of other material - very close to the composition of. The radius of the sun is about 700,00 km - 100 times more than the radius of earth. The sun is also a g2v spectral type - this address the colour of the tart how much energy it is taking out and what point of life it is at. The sun is made up of several layers.
