Secrets and facts about the sun






Sun Group
The sun follows a number of planets, which are 8 planets known and revolve around the sun. This group is called the solar system and orbits these planets in orbits around the sun from the inside to the outside like the order Mercury - Venus - Earth - Mars - Jupiter - Saturn - Uranus - Neptune.




This arrangement is divided into two outer sections of them and arranged as follows: Mercury Mercury Earth Mars
The external arrangement of them Saturn Jupiter Uranus Neptune.
The planets and other objects in the solar system are divided into three categories
The planet is a celestial body orbiting the Sun and its mass is sufficient to form its own self-attraction, which imposes the static balance of the body.






The dwarf planet is also a celestial body and has a solar orbit as well as its mass is sufficient to form an attractive and self-imposed static balance. The third category is objects other than moons and are called small asteroids.



The planets of Mercury and Venus have no dependencies and each planet follows a group of satellites or satellites. Inside the solar system there are also huge numbers of comets, there is a belt of small criminality revolving around the sun outside the orbit of Mars.
There is also a huge spherical cloud called the Oort cloud located at the edge of the solar system and surrounded by a span of 3 years. There is also a belt called Kipper and this area consists of rocks and frozen objects
. the sun
 It is one of the small stars of yellow color and not of the giant stars nor the giant, and this is what some imagine because of its proximity to the earth. They represent the main source of heat on Earth.





The sun radiates heat and light everywhere on Earth and in all directions due to the nature of the sun in terms of it's mass of inflamed reactions and nuclear mergers.
If the sun approached from the earth, the earth would burn and all of them would die, even if they departed from the earth, to freeze everything on the earth's surface.
One of the most important phenomena that occur on the surface of the sun is the solar explosions.




These explosions consist of the increase of the solar magnetic energy and thus the waves of the sun on the high glow of white light and the speed of this light about 3 million kilometers per hour towards the planet and the first to encounter this solar radiation class Air feeders that are called ionosphere. These solar explosions occur in an orderly and circular manner every eleven years.





There is another phenomenon of natural phenomena of the sun, which is the solar wind and start at a speed of 320 kilometers in the second one and its content are electrons, free movement negative and contains the nucleus of hydrogen atoms and helium and those containing positive ions. These solar wind affects the magnetosphere layer which is a magnetic layer.
The Sun has a fundamental role in the life of all living beings. For example, unlike human life, it is the main source of plant photosynthesis.



It has an internal temperature of 15,400,000 degrees Celsius.
The sun's diameter is 1392000 km.
The size of the sun is 1,300,000 times more than the size of the earth.
The sun is about 150 million kilometers away.






The mass of the sun is 73% hydrogen, 25% helium and 2% other different elements.
The sun's estimated age is 4.50 billion years.
The area of ​​the sun is 11880 times more than the land area.

The temperature of the atmosphere reaches ten thousand Calvin and there is also a region called Corona up to a temperature of a million cubic. These figures are appreciated because it is not easy to know the real numbers. The surface of the sun is colder than its atmosphere, with a temperature of about 6,000 Calvin.






One role for the sun around the center of the galaxy needs 240 million light years and this explains the impossibility of reaching the sun because it will take years of an estimated number of millions. The Sun is about 25000 light years away from the center of the galaxy and is the center of our Milky Way galaxy.





Because of the nature of the sun, the gas rotates parts of the sun at different speeds and dim and complement the sun cycle around itself at the full equator and that cycle takes 25 days and complete the cycle at the poles in 36 light years.






Astronomers believe that the sun has formed from four and a half billion years and the sun is a big star is not full age and at the full five billion years will differ the shape of the sun from the size and color.


During each second of the sun's production of energy, 700 million tons of hydrogen gas are converted into ash called helium ashes through a process called the process of fusion. This process is important to keep the temperature of the earth in moderation and that process highlights the importance of the sun to the planet and the living.
