Hot stuff
Hi, i'we always been fascinated with space and love watching Star Trek and Star Wars and other space related things. And the Sun has always interested me in a special way.
The sun is a star, Our star. And we depend on it for warmth, energy, photosynthesis to name a few. So you could say it's important for our way of life. The sun is 4.6 billion years old.
The in the center of the solar system. And its a nearly perfect sphere of hot plasma reaching temperatures of 15 million °C at its center. The sun generates a magnetic field with internal heat transfers due to bulk movement of molecules . The sun is mostly composed of hydrogen and helium. And it's massive, it's 109 times wider than Earth, it's so big that one million Earths could fit inside it, and 33,000,000,000,000,000,000,000,000 humans could fit inside it.
The sun is 149.6 million km away from the earth, that's like 194.5 times to the moon and back.
It takes 8 minutes for light to reach Earth although it will have taken the energy millions of years to reach the Sun's surface from the core.
The sun travels at 222 kilometers per second. This is 30 times faster than your average highway speeds.
The sun is the most powerful source of energy in the solar system. It’s the most energetic object for light-years in all directions.
The sun outputs 384.6 yotta watts (3.846×1026 watts) of energy in the form of light and other forms of radiation. About 10% of this output is UV radiation. The atmosphere blocks about 77% of the Sun's UV almost entirely in the shorter UV wavelengths. The sun is literally a huge fusion reactor.
You can't look right at the sun, well you can, you just shouldn't. The sun can burn a hole in your eyeball. Your retina can handle indirect sunlight just fine. But like when focusing the suns light with a magnifying glass happens with the lens in your eye when you look at the sun. This burns your retina and you become blind. Your eye cannot heal because the retina is nerve tissue, which doesn't readily regenerate.
The sun really is fascinating but scary at the same time. Thanks for reading.
Stay safe. Don't look at the sun 😂!

I never quite grasped the size of the sun until I found a random gif on the internet. And even though the sun is so massive, it’s not the biggest.

Nice gif 5/5 ending xD but yeah it's huge and to think that it will one day consume the earth after the hydrogen has burned away... but thank god that's millions of years away!
