The Sun - Center of the Solar System
The sun is a star at the centre of our solar system. It is a huge spinning ball of hot gas that lights up the Earth and provides uswith heat. Our sun is a medium-sized yellow star that is about 150 million km away from the Earth.
Here are some important facts about our sun:
* The sun is made up of over 70 % hydrogen, 27 %helium and other elements.
* On the surface, the sun has a temperature of over 5,000 ° C and in its core a temperature of a few million degrees.
* The sun's diameter is about 1.4 million km.It is 10 times larger than the planet Jupiter and over 100 times larger than the Earth. About 1.3 million Earths could fit into the sun.
* Sun is not a big star compared to others in ouruniverse.
The sun was formed about 4.5 billion years ago. As a star of the second generation, it doesn't only burn hydrogen but also other elements, like helium and metals. They were formed when a bigexplosion took place, which formed our solar system.
What are the "parts" of the Sun? Scientists who study the Sun usually divide it up into three main regions: the Sun's interior, the solaratmosphere, and the visible "surface" of the Sun which lies between the interior and the atmosphere.
There are three main parts to the Sun's interior: the core, the radiative zone, and the convective zone. Thecore is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone. Its name is derived from theway energy is carried outward through this layer, carried by photons as thermal radiation. The third and final region of the solar interior is named the convective (or convection) zone. It is alsonamed after the dominant mode of energy flow in this layer; heat moves upward via roiling convection, much like the bubbling motion in a pot of boiling oatmeal.
