TheSunis a main sequence wiz , think of that it is ‘ in-between aged ’ at 4.6 billion geezerhood previous . It has a surface temperature of some 5778 K ( 5505 ° C ) and has a diameter of about 1,392,684 kilometre . The Sun transform 620 million metric tons of H into helium each 2nd ; once this supply has work out in about 5 billion days ’ meter , the Sun will expand into a red hulk and then exit , leaving behind its core and a planetary nebula . Once the planetary nebula has dispersed into infinite , a ashen dwarf will be bequeath behind , which will also someday coolheaded and pop off .
One method scientist use to study the interior of the Sun ishelioseismology . This involve study the propagation of the waves in its body , alike to how geologists learn about the interior of the Earth by supervise seismic waves emitted by earthquakes . The wafture in the Sun ’s body cause little oscillation of the aerofoil that are evident .
There are three bed separating the aerofoil of the Sun from its substance . The inside layer of the Sun are the photosphere , the convective geographical zone and the radiative zone . The photosphere is represent of hydrogen at 5500 ° C , and is where sunspots hap . The convective zona check current which take oestrus to the photosphere , which is around 140,000 klick thick . The vigor from the centre , which is where H is transform into atomic number 2 , goes through the radiative zone , about 380,000 km thick .
The solar atmosphere refers to the parts of the Sun above the photosphere . There are five main geographical zone of the Sun ’s atmospheric state : the temperature minimum ; the chromosphere ; the transition region ; the corona ; and the heliosphere . The heliosphere extends past the orbit of Pluto to the heliopause ; here it forms a blow front edge with the interstellar culture medium . The chromosphere , transition part , and corona are all much hotter than the Earth’s surface of the Sun . Solar flares occur in the chromosphere .
NASA have developed avirtual tour of the Sun . you’re able to chatter on feature on the Sun to determine more about : sunspot ; the Sun ’s construction ; the photosphere ; solar active region ; the corona ; and the time to come of the Sun . you may also read more about the current solar deputation , ACRIMSATandSORCE . There is also a video on the Sun ’s role in climate change and some flying fact .
