THE BIGGEST STAR

THE BIGGEST STAR IN

 THE UNIVERSE 

Our Sun consists of 99.6% mass of the entire Solar System. Is not so big. It is the average size of the Star. Our Sun is a Yellow-Dwarf Star. Many stars are bigger than our Sun. But the top position is holding by two stars. Let's see about it. 

HYPER GIANT STAR:

The smallest star is Brown-Dwarf. It is much bigger than the Jupiter. Scientists make a chart to classify the types of stars by their Mass and Emission of Light. In that chart, Our sun occupies the middle position, Yellow-Dwarf. The top most position is occupied by the HYPER GIANTS. The top two is UY Scuti & VY Canis Majoris. This two Giants are almost in equal size. It is difficult to find the bigger one. Because the information we get about these stars are very low. The calculations proved that UY Scuti is bigger. Second place hold by VY Canis Majoris. Sometimes the position will change according to the size. UY Scuti is at a distance of 5500 Light Years from the Solar System. This star is very near to the SAGITTARIS ( Black Hole of Milky-Way). It emits a large amount of radiations. This UY Scuti is 1500-1900 times greater than our Sun. The diameter of this Giant is 2.3765 billion kilometers. If we travel in the speed of Light we will complete one rotation after 7 hours. If we compare this Giant to Our Sun, Our Sun will look like a Garden Pea. If we replace this Giant to the Sun, It occupies till the Saturn. The mass of this Giant is only 20-25 times greater than our Sun which is very much lesser. UY Scuti is under the category of Red Hyper Giant. This Giant increases and decreases its size every 720 days. The size can have the efficiency to burn the Fuel faster. 

UY SCUTI:

Our Sun is in the stage of converting Hydrogen to Helium and if the completion of Hydrogen, Helium forms Heavier elements. UY Scuti completely losses Hydrogen. It still lives because of Heavier Elements. May be this Giant is near to its Final Stage. It still lives only 1 million year. This Giant might have planets. But no organisms will live in it because of the Heavy Radiations emitted by the UY Scuti. The Giant is Highly Active and Emits high amount of Stellar Winds. 6seconds of UY Scuti's energy = 1 year of Sun's Energy. Suppose a planet in the Habitable Zone of this Giant, it completes its one rotation in 10,000 years. They experience 2,500 years Summer and 2,500 Years Winter.

THE CONCLUSION:

Even though these two Stars are HYPER GIANT and BIGGEST STARS. Our Sun is special for us. Because Sun only has Earth a Marvelous, Wonderful Planet we live.
