Solar System 101 | National Geographic

– [Narrator] Our solar system is one of over 500 known solar systems in the entire Milky Way galaxy. The solar system came into being about 4.5 billion years ago, when a cloud of interstellar gas and dust collapsed, resulting in a solar
nebula, a swirling disc of material that collided
to form the solar system. The solar system is located in the Milky Way’s Orion star cluster. Only 15% of stars in the
galaxy host planetary systems, and one of those stars is our own sun. Revolving around the
sun are eight planets. The planets are divided
into two categories, based on their composition, Terrestrial and Jovian. Terrestrial planets including
Mercury, Venus, Earth, and Mars, are primarily
made of rocky material. Their surfaces are solid,
they don’t have ring systems, they have very few or no moons, and they are relatively small. The smallest and closest
to the sun is Mercury, which has the shortest
orbit in the solar system at about three Earth months. Venus is the hottest
planet, with temperatures of up to 867 degrees
Fahrenheit, due to an atmosphere of carbon dioxide and
extensive lava flows. Next to this world of fire
is a world of water, Earth. The water systems on
this planet help create the only known environment in the universe capable of sustaining life. The last of the terrestrial planets, Mars, might have also supported life
about 3.7 billion years ago, when the planet had a watery
surface, and moist atmosphere. Beyond the four Terrestrial planets of the inner solar system
lie the Jovian planets of the outer solar system. The Jovian planets include
gas giants Jupiter and Saturn and ice giants Uranus and Neptune. The gas giants are
predominantly made of helium and hydrogen, and the ice
giants also contain rock, ice, and a liquid mixture of
water, methane, and ammonia. All four Jovian planets
have multiple moons, sport ring systems, have no
solid surface, and are immense. The largest Jovian is
also the largest planet in the solar system, Jupiter. Nearby is Saturn, the solar
system’s second largest planet. Its signature rings are wide enough to fit between Earth and the moon, but are barely a kilometer thick. Past Saturn are the ice
giants, Uranus and Neptune. The slightly bigger of
these ice giants, Uranus, is famous for rotating on its side. Next to Uranus is Neptune,
the outermost planet in the solar system, and
also one of the coldest. Orbiting the Terrestrial
planets is the asteroid belt, a flat disc of rocky
objects, full of remnants from the solar system’s formation. From microscopic dust particles, to the largest known object,
the dwarf planet, Ceres. Another disc of space debris
lies much further out, and orbits the Jovian
planets, the icy Kuiper Belt. Apart from asteroids, the
Kuiper Belt is also home to dwarf planets, such as Pluto, and is the birthplace of many comets. Beyond the Kuiper Belt is the Oort Cloud, a vast, spherical
collection of icy debris. It is considered the
edge of the solar system since that is where the gravitational and physical influences of the sun end. Our solar system’s
particular configuration of planets and other celestial objects, all revolving around a life-giving star, make it a special place to call home.

  1. When you think solar system formation you should think like static electricity between objects of different charge potential in the plasma vacuum of the universe…THUNDER CLAP. The body with more charge potential will connect with the less charged body and cause it to discharge matter, the same way the Mars blueberries were formed but on a much larger scale. The moon formed this way as well. You can uggffrsee it’s electric connection with the sun as it arc glows when it passes through the suns positive field on its journey through the solar system.

  2. Earth is great ,definitely recommend living on it.

    pros: good atmosphere and a lot of water
    cons: too much gravity

  3. Guys some people say that it’s a planet but scientist does research about if Pluto is a planet or a dwarf planet if they are not shown in some solar system videos it might be that Pluto isn’t a planet anymore

  4. Don’t kno why it was even classified in the first place but, bun them. Pluto is a planet to me 💓

  5. Good presentation however Big Bang and all the billions of years been quoted for the universe (our Solar system included) are nothing but unproven theories. It makes no sense that ABSOLUTELY NOTHING exploded and created EVERYTHING. The reality is that there is a GOD (who lives outside time and space) who created everything as outlined in the BIBLE.

  6. My school tell me a lesson in computer class 4 my name is Ayush Majumdar please like and share and comment my YouTube profile is like share and comment please my request. Earth is a very beautiful.

  7. Mars supported life 3.7 billion years Ago…. what about earth will it stop supporting life? I think yes because environment is totally destroyed now

  8. I dont know why, but I am kinda addicted to astronomy videos. I am now imagining of owning a house and sticking a big wallpaper of solar system. Has anyone done that? Is it normal?

  9. I've been searching on Google
    Distance between Earth and Neptune
    It says 4.3 billion kilometers.
    But didn't show how to reach via bus,train,car,walk.
    Anyways I'm gonna try other search engine to reach Neptune.

  10. Solar system is not heliocentric nor geocentric, solar system is helical. The Sun orbits in spiral motion around the orion arm and also orbits the galactic center every 230 million years creating a long sine wave like pattern. The planets orbit the Sun in spiral motion and the moons orbit the planets in spiral motion, there is no circular loop orbit. We see the moon orbiting earth in circular motion but that's just an illusion, the earth is orbiting the Sun therefore the moon is orbiting the earth in spiral motion. Stars, planets and moons create a sine wave like pattern due to the way they orbit. Youtube search "helical model of solar system".

  11. え、まって、銀河系に比べたら太陽系ってそんなに小さかったの??

  13. (KJV)Romans 1:19-20
    Because that which may be known of God is manifest in them; for God hath shewed it unto them.
    For the invisible things of him from the creation of the world are clearly seen, being understood
    by the things that are made, even his eternal power and Godhead; so that they are without excuse

  14. Am I the only one who thinks the start of this video is a lie I belive jesus built the earth he died for you and your not thanking him pleas give your life to him he loves you I almost died and he saved me
