Transcript of Planet Neptune

Planet Neptune The Rings of Neptune Introduction to Prezi The "Great Dark Spot" of Neptune Neptune is one of four planets in our Solar System with planetary rings. It has a total of 5 rings, those rings are made out of 20% dust and 70% rock and space junk. Neptune has very faint rings and they are very hard to see with a small telescope, but with a big space station telescope the vision is just perfect. The names of Neptune's five rings starting from the inner-most ring are, 1989 N3R Galle, 1989 N2R Leverrier, Lassel, Arago, 1989 N1R Adams. All 5 of Neptune's rings were discovered by the Voyager 2 in 1968. Most of Neptune's rings are faint but the 2 outer-most rings are not. Also, did you know that there are actually 9 rings of Neptune but NASA Scientists have not yet discovered them all because they are very faint. I think you enjoyed this and stay tuned for more! Conclusion to Prezi "THE BLUE PLANET" Hello, my name is Chirayu and my Prezi will be
about the planet Neptune, in this Prezi you will learn
all the Interesting things you never knew about the
"blue planet" . Also it will be a very enjoyable learning experience for you, as you learn new things about this amazing planet! Now how about I stop talking, and let you enjoy my Prezi! Neptune's Moons Neptune is a planet with many moons, in fact, Neptune has 12 known moons, the first 5 moons were discovered by the discoverers of Neptune and the next 8 moons were discovered by the Hubble Space Craft by Nasa 119 years later. The names of the Moons are, Triton, Neptune's largest moon and first moon to be discovered (10 Days after just Neptune was discovered), the next moon is Nereid, (the second moon to be discovered) 2 years after Triton was found,it is the smallest out of the 12 moons. The next moon I will be talking about is, Despina, the asteroid like moon, Despina is the warmest out of the 12. The next moon is Thalassa , this moon is unique in its own way, it has the most oxygen out of the 12 moons but it is the coldest. The 5th moon is Proteus, Proteus was an asteroid but was pulled in by Neptune's gravitational pull, it is the dustiest moon out of the 12 moons. After this moon comes the moon Neso, Neso was the first moon to be discovered by the Hubble Space Craft. This moon, Sao is the most deadliest moon, it has the most storms out of all the moons in Neptune's orbit. Larissa is Neptune's neighbor moon as it is right above the planet and scientists think there could be life on this moon because they found an amount of oxygen a little similar to Earths oxygen. This next moon,Galatea is Neptune's form of light as it reflects some of the extra sunlight and shines some of it on Neptune's atmosphere. Laomedeia another one of Neptune's moons has the longest distance away from Neptune. Psamathe is Neptune's longest moon (in size). the last moon I will be talkiing about will be Naiad the latest moon to be discovered, what makes it so special you might ask, well this moon is the size of the Earth! It is so special that us humans might call it home someday! Now these were all the moons that Neptune has to offer, but since technology is advancing these days we will be able to find all the moons in the whole entire galaxy! Basic Information : Neptune has 5 rings :Neptune is the farthest planet from the Sun :Neptune is the 8th planet from the Sun : Neptune was named after the Greek god of water
Poseidon, but by the gods alternate name Neptune. : Neptune has 13 known moons :Neptune is the coldest planet in the Solar System
because of its distance from the Sun : Neptune was discovered on September 23 1846 : Neptune is the last planet in the Solar System
after Pluto was reclassified as a dwarf planet : Neptune is an "Ice Giant" along with its counterpart Uranus. : Neptune orbits the Sun every 165 years : Neptune's length of a day is 16.4 Earth hours Unfortunately Jupiter is not the only
planet with a large spot surrounding the
atmosphere, Neptune is too, scientists all
over the world call Neptune's large spot
"The Great Dark Spot". This spot was discovered by NASA's Voyager 2 in 1989 as the spacecraft flew by Neptune. "The Great Dark Spot" is made out of Neptune's severe storms, ice caps and its hydrogen and methane filled clouds which give the spot its dark colour. Also the spot has a similar appearance to Jupiter's "Great Red Spot" but not at all in similar size. Speaking about size, did you know that 2 Earths could fit inside Neptune's "Great Dark Spot"? But gradually and slowly Neptune's magnificent spot will disappear,
the reason that is because as Neptune keeps orbiting the Sun the ice caps will start to melt and since the ice caps are what makes the dark spot cold and unbreakable it will melt and make the spot fade away but this is not scheduled to take place until 2.5 million years from now. "The Great Dark Spot" is a magnificent thing to talk about and I hope you enjoyed what I taught you today. Neptune's Moons "The Blue Planet"- Neptune has 13 moons orbiting it. Here are some interesting facts about them :
Triton-The first Neptune moon was discovered by the astronomer William Hershel along with 4 other Neptune moons,it is also the biggest. Larissa- Larissa is currently the dustiest moon found on Neptune's orbit. Neso- Neso is Neptune's coldest moon with cold temperatures going down to about -237 degrees centigrade. Despina- Despina is the smallest moon on Neptune but the closest moon to Uranus. Thalassa- Thalassa is the only moon that was once an asteroid but got trapped by Neptune's orbit. Neried-Neried is the hottest moon on Neptune reaching high temperatures to about -141 degrees centigrade which is the hottest temperature compared to Neptune's original climate, it was also the second moon to be discovered by William Hershel. Proteus- Proteus was the last moon discovered by the Hubble Space Craft on its search for Neptune's moons. Galatea- Galatea has the right amount of oxygen that we have on Earth and scientists have also discovered water on this moon but because of the very cold climate, life cannot be fully supported. Naiad was once thought of as a really small meteorite, but when scientists discovered the distance from the moon and Neptune it was reclassified as one of Neptune's moons, it was originally the third moon discovered by William Hershel. The last moon discovered by William Hershel is the moon Sao. Laomedeia is Neptune's brightest moon because of its accurate angle with the Sun when it orbits. And the next moon, Psamathe, Psamathe, is literally the last moon in the Solar System because of its far distance from Neptune. Last but not least, Halimede, this moon is one of the only moons that can be seen orbiting Neptune during an planetary alignment. I hope you enjoyed my discussion on the moons, but don't worry there is more to come! Moons of Neptune.

in my Prezi was for enjoyment &
learning opportunities, I also hope that you enjoyed what I had to say about the amazing planet Neptune. But this is not over, as the search for more mysteries about the Universe continues! The End! : 60 Earths could fit inside of Neptune Neptune rotates and/or orbits the Sun,it takes Neptune officially 165 years to rotate around the Sun once. Neptune rotates the Sun in an slant/circular fashion, unlike the other planets, they move circularly. Neptune really has no important role in the Solar System like Earth does, it cannot carry life, because of its severe atmosphere, nor can it support life because of so little oxygen. What is Neptune's movement and role in our Solar System?
