Interesting Facts about the Sun
The Sun is huge
With a diameter of 109 times the size the Earth, the Sun makes a really big sphere. You could fit 1.3 million Earths inside the Sun. Or you could flatten out 11,990 Earths to cover the surface of the sun.
The sun is hot
Within the core of the Sun, the temperature is 15 million degrees centigrade and pressure (340 billion times Earth's air pressure at sea level)
The sun gives of massive energy
The Sun's energy output, produced by nuclear fusion reactions, is approximately 3.86e33 ergs/second or 386 billion billion megawatts per second.
The reaction taking place in Sun is nuclear fusion, same as a Hydrogen bomb.
Each second 700 million tons of Hydrogen are converted to 695 million tons of Helium and 5 million tons of energy in the form of gamma rays. Each second the Sun loses 5 million tons of material.
In 40 minutes of daylight The SUN releases upon The Earth the amount of energy that is consumed by the entire population of the planet in ONE YEAR.
The energy contained in one days worth of sunlight could power the Earth for 27 full years.
It takes up to 50 million years for the energy produced at the core of the Sun to reach its surface. This then reaches the earth's surface in only 8 minutes.
If the Sun were to stop producing energy today, it would take 50 million years for significant effects to be felt at Earth.
We wouldn't exist without the sun
All the coal, oil, gas, and wood on Earth would only keep the earth warm for three days after the sun stopped shining and then mankind would cease to exist.
