Sun and its hidden facts
The Sun is considered the main star which gives vital energy to our planet Earth and to the Solar System. It is comprised of Hydrogen of 70% and Helium of 28% and remaining 2% is metal. The rotation of sun differs in the equator region and in the polar region like for example- at equator surface, it takes 25.4 days to rotate while it takes 36 days near the polar surface. This difference takes place because unlike Earth, it is a gas body and that’s why to it rotate in such manner. The temperature comprises of 15.6 million in Kelvin. Compare to water, core centre of its density is 150 times more.
Sun and its Power
Sun and its power are of 386 billion Mega Watt and it is produced with the help of reaction of nuclear fusion. In every second, Hydrogen of 700,000,000 tonnes converted into Helium of 695,000,000 tonnes. The energy of 5,000,000 tonnes is converted into gamma rays. The energy gets absorbed because of its outward movement across the surface area and discharge temperature at a low rate and till it reaches the surface it becomes a visible light. 20% path of the surface is moved not with radiation but with convection.
Story behind Solar Eclipse
Photosphere is the surface of Sun and it has a temperature of 5800 K. The Sunspots are large and has a diameter of 50,000 km and they are a very cool region as to be considered. These Sunspots are formed due to the magnetic field interaction of the magnificently bright star.
Above Photosphere lies chromosphere and Corona lies above chromosphere and it is highly spread in space, but during solar eclipse (total) Corona is visible. 1,000,000 K is the total temperature of Corona. From Earth, Moon and Sun it appears to be the same size. Moon generally rotate around Earth and Earth rotate around Sun and both orbits are in the same plane. Sometimes, Moon comes in between Earth and Sun and cause Total Solar Eclipse and when Moon rotates slightly imperfect then it is Partial Solar Eclipse. During the daytime, it becomes almost dark at the time solar eclipse and it is amazing because you can see stars in the sky and birds and animals think it is night time. It is simply incredible.
Sun as Energy Booster
Sun also leaves solar wind of low density of about 450 km in per second. This solar wind offers the highest form of energy and it has a strong effect on our Planet Earth. Solar wind composition is different in the different polar region.
- Diameter: 1,390,000 km
- Mass: 1.989e30 kg
This star is a source of energy and gives us light so to survive on this beautiful planet. It has both visible light and ultraviolet light and both has a strong impact in our life. Visible light of this star has vitamin D which is good for human health while ultraviolet rays cause skin cancer and other serious diseases. The age of Sun is 4.5 billion and it used only ½ quantity hydrogen, but one day the hydrogen fuel of Sun will end and this will cause Earth’s destruction.
