The closest star to our planet is Sol which is Latin for the sun. For billions of years the sun has been there to provide us with, life, light, and heat. Although the sun gave us life, but can we really feel safe, because the can kill us anytime without much warning. Even though it gave us life it was still looked upon as a mysterious object.

The sun and the whole universe were once thought to revolve around the planet earth, but we found out that the earth and the other planets orbit the sun and there is no center of the universe.

The Sun has seven layers the light takes a journey from to another. First Nuclear Fusion occurs when hydrogen atoms ram into each other with such force that they produce on helium atoms, which is what make the light particle. The Radiation Zone is the next layer which they enter once they are created. They enter this as Electromagnetic Radiation; however, it will take them millions of years to get out of this layer. After the fight with the Radiation Zone they enter the Convection zone, and they now must escape in convections. A lava lamp is the best thing to compare the convection zone with because they both rise on heat. Then it is to the Photosphere which is the place that sends it to the planets. The journey through the sun has ended and the light reached the planets. The Solar atmosphere has layers just like the plasma Surface. Chromosphere is visible during a solar eclipse as the color on the rim of eclipse. The Corona is in control of the Solar wind and the Heliosphere. The heliosphere is the amount of magnetic control the sun has.

The sun will end one day and this is how it may go, the sun will enlarge enough to engulf Mercury and Venus the earth may be able to move away to escape engulfment, by that time the earth will be a barren place anyway. Like your science teach told you, for every action, there is an equal and opposite reaction. The action was the sun giving earth life, and the equal and opposite reaction is the sun ending that life.

The solar system is very big but about 99.8 % of the solar system’s mass is the sun. Everything orbits around the sun, and it is responsible for all life found on earth. Sol is composed of Hydrogen and Helium, the hydrogen is 74 % of the sun’s mass and the Helium is 25% the sun’s mass. The Hydrogen is 92% of the sun’s volume; hence, the Helium is only 7% of the sun’s volume. The sun uses a process call nuclear fusion to make light and heat, and the way that is done is by hydrogen atoms knocking into each other at such speeds that they become helium atom and they let off energy called a pharos they take millions of years to get to the surface of the sun, but they only take about ten days to get to the planets.

For 4.5 billion years the sun has been there to give us light and heat and life as well, but it is about halfway through its supply of fuel. More than 4,000,000 tons of matter is converted into energy within the Sun’s core. The sun is a main sequence star and it will continue to be for 10 billion year when the sun runs out of fuel. A yellow dwarf is the astronomical term for the type of star that the sun is, it also says that those stars don’t have enough mass to go super nova. 4 or 5 billion years the sun will enter the red giant phase, the outer layers will expand as the hydrogen Fuel in the core Contracts and heats. After the red giant phase it throws off its outer layers and that leaves the core to slowly cool until it fades into a white dwarf which is the most powerful star in the universe, and it will take billions of year for that to happen.
