Sun 101 | National Geographic


While billions of stars are scattered throughout the universe the one at the center of our solar system Plays a special role for us here on earth our Sun formed about 4.5 billion years ago in the Milky Way galaxy’s Orion’s fur It was born when a cloud of dust and gas known as a solar nebula Collapsed and in the middle of this formation matter condensed into a burning ball of gas that became our Sun The sun’s fiery nature along with a tremendous gravitational pull and an extensive magnetic field Helped it to become the heart of our solar system The Sun can be divided into six layers or regions the corona the chromosphere the photosphere the convective and radiative zones and the core in terms of atom count the Sun is about 91% hydrogen the sun’s fuel eight point nine percent helium and point one percent heavier elements such as carbon and nitrogen Due to the sun’s extreme temperatures these elements stay in a gas like phase called plasma In the core temperatures reaching at least 27 million degrees Fahrenheit Combined with the sun’s powerful gravity fused together hydrogen molecules to create helium Called thermonuclear fusion this releases an enormous amount of energy in the form of radiation Electricity solar wind and as we experience on earth Life-giving heat and light Such volatility is contained. Thanks to the sun’s tremendous gravity It’s strong enough to hold the solar system intact and is primarily due to the sun’s size and mass Our Sun is the largest and most massive object in the solar system it’s more than 100 earths wide and Could theoretically fit all eight planets inside nearly 600 times It also contains approximately ninety-nine point eight percent of all the mass in the solar system Because of this mass the Sun has a great pull on the fabric of space Creating a gravitational force that causes nearby planetary bodies to be drawn toward it This gravitational pull allows the Sun to hold together a system of eight planets potentially dozens of dwarf planets at least 170 moons and countless comets and asteroids Without the sun’s gravity these celestial bodies would drift off into deep space Another critical property of the Sun is its magnetic field which encapsulates the entire solar system Called the heliosphere this force field protects the planets from harmful cosmic radiation It’s caused by the sun’s plasma pushing electrically charged particles toward the Stars poles This process turns the Sun into a giant magnet Although the sun’s magnetic field is invisible to the naked eye Its effects are noticeable On the sun’s surface are dark areas called sunspots, which marked strong pockets of magnetism on Earth and on some of the other planets the sun’s magnetic field interacts with their atmospheres resulting in beautiful Aurora’s Despite its size and strength the Sun will not last forever in about 6.5 billion years it will run out of its hydrogen fuel Expand to envelop Mercury Venus and even earth and then collapse into a small star known as a white dwarf in The meantime the Sun will continue to play a critical role in the system that bears its name the Suns protected magnetic field Tremendous gravitational pull and ability to create vast amounts of energy will protect Contain and give life to our solar system

  1. While the sun's heat and light are most visible to us, it has many other important capacities. What new facts did you learn about the sun's critical role in the solar system?

  2. So you got the core of the planet you live on wrong and you expect us to believe you know the core of the sun. When will you ever give up.

  3. These types of video remind you how small and insignificant life is. We are nothing but small specs of dust in a big universe.

  4. Will we be able to develop warp speed capable spacecraft that can reach other solar systems with habitable planets before our sun dies?

  5. Our universe are billions years old, but we look like as if we are alien in this universe and out there should be an intelligence life capable of using advance technology ,as there are trillions of galaxies.

  6. Stupid people who don't understand something they just say God did it, they don't even know how rain works, it's "God did it" ๐Ÿคฃ๐Ÿคฃ๐Ÿคฃ

  7. Did you guys know that there are living things in the sun they can live there cause they need a lot of heat to survive

  8. I like and love the Sun โ˜€๏ธ! But unfortunately, the sun ๐ŸŒž is making people very tired ๐Ÿ˜ด, lazy, and very self-centered about using their very limited human body energy held within the inside of the back of the human body.

  9. And there are people out there who think the sun is their friend!! SMH. Watch ONE STRANGE ROCK DOCUMENTARY hosted by will Smith. Amazing

  10. Wow, it's interesting channel, and I love this video very much.
    I love to learn more about the stars ๐ŸŒŸ and the Galaxy, and the cosmo and beyond our solar system.
    Thank you so much for amazing creations. ๐Ÿ‘ ๐Ÿ‘ โ™ฅ๏ธ ๐Ÿ’ž๐Ÿ’๐Ÿ’๐Ÿ’๐Ÿ’๐Ÿ’๐Ÿ’

  11. Bagaimana caranya mengetahui apa yang ada di dalam matahari???cahayanya ke Bumi saja sudah panas apalagi mendekat apakah ada alat untuk mendeteksinya???

  12. Theres bigger planets then the sun
    Actorius is 160000 time bigger then our sun
    Alpha Scorpi A is 2.9 million times bigger then our sun
    VY Cornius 1100 is 5.9 billion times bigger tgen our sun

  13. I always thought of the Sun as a scary being that could kill us with a solar flare but this videogave me a more calm attitude towards it. It gives life. Its gravity and magnetism protect us from the dangers of the Galaxy. Good video.

  14. the information is cool and the only bad about this channel is that the videos are shorts, I would like the videos about national geographic will be more extensive and thanks a lot, god bless u.
