Neptune 101 | National Geographic


(mysterious music) – [Narrator] Along the dark edges of the Solar System, it floats. Anchored by a star but
barely graced by its warmth, this traveler drifts alone as deceptively calm and
elusive as the deep blue sea. Neptune is the eighth planet from the Sun. At about 30 times the distance between our star and the Earth,
or 30 astronomical units, Neptune is the most distant
planet in our Solar System. This distance creates the longest orbit of the eight worlds, about 165 years, with the seasons lasting little
over 40 Earth years each. Being so far away from the
heat and light of the Sun, Neptune is cold, dark, and icy. At its heart is a solid core about 1.5 times the size of Earth. Making up about 45% of the planet’s mass, the core is made of water
ice and silicate rock. The rest of the planet is believed to be a hot pressurized ocean of
water, methane, and ammonia ices surrounded by a layer of clouds. These clouds, predominantly
made of hydrogen and helium, include traces of methane, which give this ocean
world its rich blue color. While the clouds create a
cool, calm veneer from afar, up close, they are whipped around by the most severe weather
in the Solar System. Winds on the planet reach speeds of over 1,200 miles per hour,
nearly five times faster than the strongest
winds recorded on Earth. In fact, the winds are so powerful that they break the sound barrier. Drifting high above this windy ice giant is a quiet ecosystem of
rings and satellites. Six rings encircle the planet, with some containing ring arcs, or clusters of dust particles in a ring. Also revolving around the
planet are 14 known moons, with the largest called Triton. Named after the son of
the ancient Greek sea god, Triton has ice volcanoes
and may even contain a subsurface ocean. Much is left to be
discovered about Neptune, its rings and its moons. Only one spacecraft, Voyager 2, has visited these cosmic bodies, but future missions to
this mysterious icy world would have even more stories to tell.

  1. As the most distant planet in the solar system, it takes Neptune about 165 years to travel around the sun. To learn more about about this blue world, read on here: https://on.natgeo.com/2I3M5Xc

  2. كذب وخداع لا أصل له
    – الأرض ليست كروية.
    – لا وجود للفضاء المزعوم.
    – لا وجود للأقمار الصناعية ( محطات بث أرضية).
    اللهم بلغت..

  3. This planetary system consists of just the 1st Heaven… The 1st sky. There are billions of galaxies in this universe with massive black holes in all of them. All of this is the Creation of Almighty Allah… The Great and The Most Powerful. He is the Creator.
    May Allah guide all of us towards the right path.

  4. Yea neptune is probobly my favorite planet in our solar system becuz the it it . It is cool ahahahaha really funyy hahahaha. No?

  5. It's amazing that there is this planet and satellites with their own dynamics and there is no one to observe it.

  6. Neptune's pretty cool but 40+ years of winter? No thanks! xD I can't even handle a few months of winter. Lol.

  7. Winds breaking the sound barrier? At which atmospheric pressure's corresponding sound barrier: Earth's or Neptune's? I can go on: At which layer's atmospheric pressure's sound barrier? Etc etc. Please be more specific. Otherwise very nice video, National Geographic!

  8. Even though, you and I might be only a few thousand miles apart, somehow I can still feel the beautiful warmth of your voice..

  9. If I had the power of immortality and I was immune to everything in existence including withstanding the deadly power of solor system and can travel the speed of light times infinite and still can't die I would want to visit every planet here in this universe and come back to earth just to be the first person to visit all planets. Just a cool thought but in reality yeah that's not gonna happen anytime soon

  10. How do they know winds are 1,200 mph? I mean, one satellite ever has briefly flown past it, how can they know what they’re reporting is accurate?

  11. National Geographic:Neptune is the most distnat and last planet from the solar system
    and shows 8 planets
    Pluto: am i a joke to you?

  12. c'est une honte des mensonges pareils , Neptune est la première née de notre système solaire, avec maintenant une atmosphère conséquente, et elle sera bientôt dans un futur proche un soleil , progression naturelle de l'électromagnétisme, alors quand on ne sait que les planètes sont des aimants on se tais , car malheureusement vos connaissances de l'univers du créateur sont nulles,

    a travers les écrits du fils de l'homme (annoncé dans le nouveau testament )et sa parole de vérité,notre Créateur nous fait découvrir son univers vivant,simple ,génial, crée pour lui même et tous les humains (Adans et Eves )de toutes les terres dans chacune des galaxies sans nombre de cet immensité.

    encore faut il en prendre connaissance, et accepter cette réalité avec modestie.

    prenez donc le temps de lire LE LIVRE DE VIE de l'agneau,(.com) PDF gratuit, et la vous verrez que ce vous observez depuis la terre est bien loin de vos divagations impossibles
