The SUN

THE SUN

                       The Sun is a star in the center of a solar system and Sun is the largest in size compared to all solar planets. The Sun is head of solar system. It is an almost complete spectrum of thermal plasma, in which the nucleus heats up due to fusion interactions, distributing energy mainly as visible light and infrared radiation.  He is the most important source of energy for Earth's life.  Its width is about 1.39 million miles (864,000 km), or 109 times higher than the Earth. Its size is about 330,000 times greater than Earth and about 99 times greater than Earth.  86% of the total weight of the solar system. Three-quarters of the sun's weight is made up of hydrogen (~ 73%). the other is mainly helium (~ 25%), which has very small amounts of heavy metals such as Oxygen, Carbon, Neon and Iron. The Sun is a star in the main sequence of type G (G2V) based on its observable phase.  Therefore, it is not called the irregular and completely clear yellow back (its light is closer to yellow to white). It was about 4 p.m.  Six billion years before gravity falls on a vast cloud mass of cells.  Most of these objects are centered in the center, and some line up into a space disk that has become a solar system.  The medium weight became so hot and hard that it finally began to bind to the nucleus.  It is believed that almost all stars are formed by this process. 

                                                                       

     

                      The Sun today contains about 600 million tons of hydrogen per second in the center of the sun, converting 4 million tons of energy per second.  This energy, which can take 10,000 to 170,000 years to evaporate from the nucleus, is a source of sun and heat.  The concentration of hydrogen in its shell When the Sun is no longer in the same hydrostatic position, its core causes a significant increase in volume and heat, the outer layers grow and eventually the Sun becomes a giant red.  It is estimated that the Sun will be large enough to swallow the current cycles of Mercury and Venus and make the Earth uninhabited, but not for five billion years.  After that, it releases its outer layers and becomes a cool constructed star called the white dwarf, which no longer exerts energy by merging, but burning and releasing heat from the previous assembly. The influence of the sun on Earth has been felt throughout history.  Some cultures view the sun as a god.  The synodic exchange of the Earth and its orbit around the Sun forms the basis of the solar calendars, one of which is the Gregorian calendar, the calendar used today. Sun is two homophones words one is SUN another one is SON. SUN= means star and SON means a boy or man in relation to either or both of his parents.
