Our Sun - The Study of a Star

Authors note: This is my project on The Sun and what it does. It is an essay and its my first essay of the year, so if you have any suggestions on how to make my next one better leave a comment. Enjoy!

 

Many people think that the world will end when the sun dies or in 2012 but in reality the world will end when the sun turns into a Red Giant. When the sun turns into a red Giant it will increase in size and mass  and that will affect the Earth a lot since we are close to the sun.  The sun will get so big it will burn up our planet and any planets closer to the sun than us.  The heat will also have an affect, it will get a lot hotter than is ever was before. Then the earth will start to heat up and start having a lot warmer weather.

When the Sun turns into a Red Giant it will increase in size to about 10-100 times the current size. It's current size is 11,990 Times the Earths surface area. It will completely absorb Mercury, Venus, Earth, and Mars! Its Mass will also grow by about 10-100 times the amount it is now. It's current mass is 333,000 times Earths Mass! The Sun won't only burn up our planet but completely obliterate it!

The Sun will also heat up from around 1,000,000 K to about 100,000,000 K! (Kelvin is a different way to measure temperature.) This will burn up everything on the planet, including us! The Earth will start to burn up from the outside, to the core and then nothing. The sun will then continue to heat up until it starts to run out of hydrogen to fuse and it will turn into a White Dwarf. After that the sun will be nothing and the solar system will be dead.

The Sun turning in to a Red Giant is an obstacle that we can't avoid and it will lead to the end of the world. Now we can all stop thinking that the world is going to end so soon, like next year, Because the sun won't turn into a Red Giant for about 3.5 to 5.5 Billion years. The Sun will be the only thing causing the world to end.
