Taking a Closer Look at the Sun - 697 Words

The Sun is the largest star and object in our solar system with a diameter of 1,390,000 km or 109 times the diameter of the Earth. It also contains 99.8% of the entire mass of the solar system. It is so large that you could fit 1.3 million planets the size of the Earth into the Sun. It is made up of 73% hydrogen, 25% helium, with the other 2% being comprised of other chemical elements such as carbon, oxygen, nitrogen, magnesium, and iron as well as others. The temperature of the surface of the Sun is 5800 Kelvin so no matter can survive as a liquid or a solid and must remain a gas. It is so hot that many of the atoms become ionized, or stripped of one or more electrons. The Sun is comprised of six parts: the core, the radiative zone, the convective zone, the photosphere, the chromosphere, and the corona. The core is where protons are merged together to form atoms of helium, releasing tremendous amounts of energy. It is approximately the inner 25% of its radius and the temperature is 15.7 million kelvin. The pressure is sufficient to support nuclear fusion and the density is more than 150 times that of water. Outside that is the radiative zone, where photons of gamma radiation created in the core are emitted and absorbed by hydrogen atoms. A single photon can take 100,000 years to finally get through the radiative zone. Outside the radiative zone is the convective zone, where bubbles of plasma rise and fall like a lava lamp. The photosphere is the layer where the Sun becomesShow MoreRelatedEssay on A Magical Forest666 Words   |  3 Pages A Magical Forest The sun is high above me and I walk into the forest in front of me, which I hear calling me.
