How amazing is our sun.

The image is from NASA’s Solar Dynamics Observatory (SDO) and shows half million mile long, whip-like solar filament, which is a cooler cloud of material that held above the sun's surface by magnetic forces.  extending over half a million miles in a long arc above the sun’s surface.

It is 109 times larger than earth.  You could put about 1 million earth's inside the sun. But if you could crush the earth into granules, you could fit approximately 1.3 million earths into the sun. 


There is so much pressure and heat in the core of the Sun that nuclear fusion takes place: hydrogen is changed to helium.   Nuclear fusion creates heat and photons (light). The sun's surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius). The amount of solar heat and light is enough to light up Earth's days and keep our planet warm enough to support life.
