Hello Trybe family , have you ever being so hot, and help but wonder how fun things will be without the Sun up there trying to cook our brains with its eternal inferno? Well, if you live in a third world, humid nation as myself, you will know that that feeling isn’t nice. With the failed institutions and difficult economic situation, life can be hard with the Sun angrily blaring down at you. So, I had to do a little research about the Sun, and what it means to our world, and the result is quite frightening.
The good news is that someday, the Sun will die and that bad news if when the Sun dies, all of humanity and all the life forms on Earth will die shortly after the sun’s death. Just like everything we know, the Sun also has a lifespan, it is estimated to have a lifespan of 10 billion years, and the star is said to be around 4.5 – 5 billion years old, meaning it has lived half of its lifespan. It is very frightening to know that the sun will probably consume our little Earth sometime in the future
About the Sun
Sol, as it is alternatively known as, is the star of the milky way galaxy, the galaxy we call home, its shape is almost a perfect sphere and it is known as a hot ball of fire. The Sun is really powerful, as it is mainly composed of gases, it is the primary energy source for life on Earth, as well as the weather and the various climatic conditions. It is really massive in size, in fact, it is estimated that if the Sun was a bowl, 960,000 earths will be perfectly inserted into the Sun.
As mentioned earlier, the Sun is about 4.6 billions years old, andit accounts for the vast majority of the entire Milky way solar system’s mass, which is about 99.86% of the entire solar system. It is spherical in shape, well almost spherical, and is made up of gases. It is mainly composed of hydrogen, and a little helium at a 70/30 ratio. The Sun is incredibly hot, with the interior of the star reaching an unbelievable 15 million <sup>O</sup>C. The heat of the Sun comes from a process that happens at its core, a process that involves the conversion of hydrogen to helium, commonly known as hydrogen fusion, that is why the internal temperature is so high, at the surface of the Star, temperatures are about 5,600<sup>O</sup>C.
Other facts about the Sun
The distance between Sol and Earth is approximately 150 million kilometers, and if light is travelling at the speed of light (300,000 kilometers/secs) this means that light from the sun takes 8 minutes, 20 seconds to reach the earth, and the heat energy we feel on the earth takes some minutes to reach us here on earth, but it take millions of years to travel from the Sun’s core up to its surface.
The sun produces charged particles known as solar wind, which travels through our solar system at an incredible 450 kilometers per second. The sun weighs an approximate 1.989 x 10<sup>30</sup>Kg, and has a radius of 695,508km
The sun as we know it is the center of our solar system, it possess a strong magnetic field. A concept known as Solar flares frequently happens on this star, and it involves the release of magnetic energy by the Star body at the event of magnetic storms. These are evident on sunspot, which reveal twisted magnetic lines and spin.
Future of the Sun
As I mentioned earlier, everything has a lifespan, and the Sun is no exception, the hydrogen fusion or fusion fusion reaction that goes on at the core of the star is basically, the conversion of hydrogen to helium. And just like every resources, one day it will eventually run out of stock/supply, and when this happens, that will be the beginning of the end of the Sun as it will mark the death of the star solar body. After the final supply of hydrogen has been expended by the Sun, the star will still be able to perform its duty for approximately 130 million years.
This time, the sun will be burning helium, during this period, it is forecasted to engulf Mercury and Venus, and then it will eventually engulf the orbit of the our little Earth, other scientists argue it will engulf the earth completely, I guess we just have to wait and see. At this stage of the Sun’s life, it will enter the red giant phase.
The red giant phase will be preceded with the collapse of the star, which will also maintain its enormass weight, but the size will be similar to that of the earth, at the point, the Sun will have been said to have become a white dwarf.
The future of the sun doesn’t look so bright
