Published on

Hello, I’m Paul. I’m living in France. I am a student of Bachelors Part – 2 and a book wormer. I love science and I prefer to search for information about science. I want to have some necessary knowledge about science. I especially draw my attention in science-astronomy. I introduce my website, which contain the useful information about Neptune planet and some Facts about planet Neptune. There are also some pictures of Neptune. I hope that, they will provide to you useful knowledge about astronomy in general and Neptune in particular.

Facts about the planet neptune

  1. 1. Interesting Neptune facts The discovery and even the naming of the planet Neptune have a veryinteresting story behind it. These are probably the Neptune facts that you weren’taware of before. Technically speaking, the very first one who became aware of the planet Neptune’s existence is the famed ancient astronomer Galileo. But the discovery of Neptune isn’t credited to him because he misrepresented it in his findings; instead of a planet he labeled Neptune as being a star. The actual discovery of Neptune wasn’t done in the usual means that you might be thinkingof; with the use of star charts and a telescope. The discovery of Neptune wasactually “predicted” using mathematical formulas. In 1846, a Frenchmathematician named Urbain Le Verriere calculated that in a specific area in outerspace, a new planet is highly likely to be discovered. So he got the services ofJohann Gottfried Galle of the Berlin Observatory to search in the area he pointedto, and sure enough there was the planet Neptune. After the discovery of the new planet there was quite a stir as to what namethis new planet should be. Numerous names began flooding the astronomicalsociety, names like Janus, Oceanus, and others. Le Verriere was actually the onethat first suggested that this new planet be named Neptune, but he changed hismind after a couple of months and tried to name the planet after himself.Obviously this came against a lot of contention in the scientific community, after
  2. 2. much debate it was decided upon that from here on in the new planet will benamed Neptune, after the Roman god of the sea, it also fits in well with the namesof the other planets in the solar system, all of which, except for Earth, is namedfrom ancient Roman deities. Here are some more interesting Neptune facts that you should know: 1. Because Pluto has been relegated into being just a planetoid and notactually a planet, Neptune has become the planet that is farthest from the sun. 2. Ever since it was discovered in the year 1846, Neptune has yet tocomplete one full orbit around the sun. Because of its extremely large solar orbit,it takes about 167 earth years before one year in Neptune is said to pass. 3. Even though the year in Neptune is longer, the days are extremely shorterthan they are here on earth. For Neptune to fully rotate about its axis, it only takesabout 16 hours, as compared to the 24 hours it takes for Earth. 4. Neptune has almost the same gravitational pull as Earth. You will onlyweigh about 17 percent more on Neptune than you would here on Earth, which isreally a negligible amount if you think about it. 5. Neptune is the coldest planet in the solar system. This record was onceheld by Pluto, but because it’s not a planet anymore; the distinction of coldestplanet now goes to Neptune. How cold is it on Neptune? It’s so cold that it wouldmake the South Pole look like the Caribbean in comparison. These are just some of the fun Neptune facts that you might not have knownuntil now. If you want to learn more about Neptune and the other planets as wellyou can visit one of the numerous websites online that are about the solar system.
  3. 3. Planet Neptune – What Makes This PlanetInteresting? There are a lot of things that are interesting about the eight planets in oursolar system, Neptune. Here are some of them: Fact No. 1 – Neptune is now the farthest planet in the solar system You may have first thought that the planet Pluto is farthest planet, that was before Pluto was stripped off of its planet status and is now considered as a planetoid. This decision made the planet Neptune the farthest planet from the sun by default. And being the farthest planet, Neptune also got the title of coldest planet. With temperatures reaching -2000 degrees Celsius,the planet Neptune makes the South Pole a great summer vacation spot. Fact No. 2 – Galileo was the first to spot Neptune Famous ancient astronomer and father of modern astronomy Galileo Galileewas I fact the first person to ever discover the planet Neptune. But why is it thatthe discovery isnt credited to Galileo? Well what happened was that Galileo didspot planet Neptune as he was mapping the heavens, but he thought that it wasonly a star and so labeled it as such in his charts. Due to his blunder at misrepresenting the planet Neptune, Galileo was neverrecognized as the true discoverer of the planet. Fact No. 3 – The planet Neptune has the longest orbit among all the planets
  4. 4. Even before Pluto was declared as just a planetoid, Neptune already had thebiggest orbit in the solar system, because there are certain areas along its patharound the sun where Neptunes orbit was bigger than that of Plutos. In fact, the orbit of Neptune is so large that since its discovery in 1846,Neptune still has not finished one complete orbit around the sun. It takesapproximately 165 years here on earth before a single year in Neptune shall pass. Fact No. 4 – Neptune was discovered using math You must have thought that astronomy is done using high-poweredtelescopes and star charts, but math also plays a critical role in astronomy. It wasFrench mathematician Urbain Le Verrier who first came up with the mathematicalfindings that there will be a new planet in the area in space that Neptune nowoccupies. After he has made this conclusion he asked for the help of astronomerJohn Gottfried Galle, Galle, using a high powered telescope scanned the area inthe sky where Le Verriers computations pointed to, and sure enough the planetNeptune was there. The even more astounding fact about Neptunes discovery is that thecomputations of Le Verrier regarding the location of Neptune are only off by onedegree. Fact No. 5 – Neptune has its own “Great spot” You have probably heard about Jupiters great spot; a violent storm that hasbeen occurring on Jupiters surface, but did you know that Neptune also has itsown great spot. Neptunes great spot is not as big as that of Jupiters but it is stillvisible. There was a time when the spot on Neptune was not visible toastronomers, so they thought that the storm has dissipated, but it resurfaced againlater, but this time on the other side of the planet. These are just some of the facts that make the planet Neptune veryinteresting.
  5. 5. Strange Behavior from Jupiter and Neptune If you’re an astronomy buff then you’d be highly interested in what’s goingon in the skies right now. Astronomers have found out that the planets Jupiter andNeptune are showing strange behavior that has not happened in a couple ofdecades. It is quite typical for the planets Jupiter and Neptune to pair off every 12 or 13 years, but for them to conjunct each other three times happen very rarely. For a triple conjunction to happen, the two planets must arrive at the point in space that is opposite the sun, called the opposition, at almost exactly the same time. This year, Jupiter will come at opposition on August 14, while Neptune will get there by August 17, and forseveral months before and after, these two planets will move in a reverse motion tothe surrounding stars, this movement is what’s called “retrograde motion”. Duringthe retrograde motion the planets Jupiter and Neptune will pass each other inopposition not just one time, but about three times total. The last time thisphenomenon of triple conjunction happened was in 1971, then next time isestimated to happen in between 2047 and 48. If you’re a novice astronomy buff who has still not seen the farthest planet inthe solar system, this is your chance to do so. Being the farthest planet from thesun (Pluto was stripped off of its planet status and just relegated into a planetoid in2006), Neptune is probably the hardest planet to spot because it is not really allthat visible, you can only see a faint glimmer of it in a completely dark night. Because of these pairings it will be much easier to spot where the planetNeptune is. By using Jupiter as your guide, train your binoculars, telescope or any
  6. 6. kind of viewing apparatus you have on it, you’ll be able to see a faint, rather bluish“star” right above it, that “star” is actually the planet Neptune. Keep your eyespeeled because spotting it can be rather difficult because Neptune won’t be asbright as Jupiter, in fact it will only be about 1/13,000th the brightness of Jupiter,so you’ll really need to have a strong telescope to even see a speck of it. This strange behavior of Jupiter and Neptune also carries a couple of different meanings in astrology as well. It is said that during this triple conjunction period there is a huge chance for success in a couple of different professional careers like legal works, travel, journalism, philosophy, and others. So if you are in those fields of work then you are now extremelylucky. And then there are others who say that the conjunction of Jupiter andNeptune also brings bad luck, it is said that the last time they were in conjunctionwas the day that the launch of the space shuttle Columbia ended in tragedy. Butthe one that is going to happen soon is a triple conjunction, so the outcome maystill be up in the air. Whatever reason you have for observing this strange behavior of Jupiter andNeptune, be it for scientific curiosity or for astrological purposes, thisphenomenon only happens once every couple of decades so missing it as ithappens will be a great loss for you.
