How does Pluto in retrograde affect us?
442092
No effect at all.  In fact when I run simulations of solar system dynamics I regulalarly exclude Pluto from my calculations when I am focusing on things in the inner solar system.\n\nA planet "in retrograde" just means that as viewed from earth they are moving "backwards" on the sky, they do this every time we catch up to and pass them in our orbit.  Pluto "retrogrades" every year.

The International Astronomical Union decided that Pluto was no longer a planet. The reason is that while Pluto is round, orbits the sun, and has three moons, it has not cleared (via gravity) its own orbit of debris.  Instead, they decided to classify it as a "dwarf planet".\n\nSee the details below.\n\nRESOLUTION 5A\nThe IAU therefore resolves that "planets" and other bodies in our Solar System, except satellites, be defined into three distinct categories in the following way:\n\n(1) A "planet" [footnote 1] is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.\n\n(2) A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape [footnote 2] , (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.\n\n(3) All other objects [footnote 3] except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".\n\n\nFootnote 1: The eight "planets" are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.\n\nFootnote 2: An IAU process will be established to assign borderline objects into either dwarf planet and other categories.\n\nFootnote 3: These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.\n\nRESOLUTION 6A\nThe IAU further resolves:\n\nPluto is a "dwarf planet" by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.

In their current orbits, Pluto and Neptune will never collide, since Pluto is in a 3-to-2 resonance with Neptune.  That means that for every two orbits of Pluto, Neptune executes three orbits; thus, they’re never close to one another in their trips around the Sun (instead, Neptune is always 90 degrees ahead of or behind Pluto when Pluto is closest to the Sun).  Even though the orbits of Neptune and Pluto seem to overlap, they will never actually collide.\n\nMany of the newly-discovered objects (hundreds of ’em now) out near Pluto have these kinds of resonances.  If they didn’t, they’d be more likely to collide with Neptune, and Neptune is probably responsible for shepherding them into these stable configurations.\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

This situation is the natural result of one body orbiting another.  It is called tidal locking.  All of the moons of Jupiter are tidally locked to it, and Pluto and it's moon, Charon are tidally locked to each other for example.\n\nWhat happens is that an object that is rotating faster than it is orbiting feels a torque from the tidal force (differential gravity) exerted across it by the object it is orbiting.  Over time this will cause the rotation period to slow down to match the orbital period.  The time this takes depends on the distance between the two bodies and the reletive masses, as well as a few other factors.

This issue is very similar to the asteroid belt issue some 150 years ago.  When the first asteroid, Ceres, was found, it was considered a planet.  Only after 15 other "planets" were found in the same orbit regime did astronomers downgrade these asteroids to "minor planets" some 50 years after Ceres' discovery.\n\nIt's unclear if Pluto could ever clear its orbit...it crrently has only 7% of the mass of its orbital neighborhood (as opposed to, say, Earth, which contains some 99.9999% the mass of its orbital neighborhood), so it's only cleared a tiny fraction of its orbit throughout the entire age of the Solar System, 4.5 billion years.\n\nMoreover, other objects in Pluto's orbit (and pluto itself, in fact) are trapped in a 3:2 orbital resonance with Neptune.  This means these "plutinos" are in a very stable orbit, unlikely to be scattered away unless something very big and unexpected comes along.

Pluto's atmosphere is super thin and transient, so I would call it's entire atmosphere a "special phenomena."  Pluto more than likely only has an atmosphere when it is at the point of its orbit that is closer to the sun (periheion).  As Pluto continues on its orbit it moves further away, and the flux of light from the sun will more than likely no longer warm the planet woungh for it to maintain the atmosphere.  What little thin atmosphere Pluto has now will freeze to the surface of the planet over next few decades.

Nice links. I would think that Pluto is still a planet. Its mean radius relative to earth's radius is approximately 0.46. So the diameter at equator might be some 3600 miles. By comparison, a satellite like Nereid, which orbits the planet Neptune, is no more than 200 miles in diameter. At its size Pluto must be a planet.\nI am not sure about Sedna. If we think about the 10-th planet, or the "X" planet, it was thought to be three times as massive as Saturn, and nearly six billion miles from the earth. It looks to me that Sedna might not be our 10-th planet. But then again, perhaps we just have to wait and see.

http://en.wikipedia.org/wiki/Pluto\n\non 24 august 2006, the international astronomical union reclassified pluto.\n\npluto does orbit the sun, is ball-shaped and is not a satellite, but it does not have an isolated orbit (a bunch of other similar bodies have similar orbits.) so it is not a planet.\n\ni have been waiting for this since i was about ten when i learned that pluto didn't fit the pattern set by the major bodies in the solar system so it was an anomaly. it just felt "out of place". now that astronomers have found hundreds of other bodies with similar orbits, classifying "134340 pluto" as a planet is even more irrational. i feel somewhat satisfied, but i don't know how long this will drag on tho. many planetary astronomers are satisfied that the definition is rigorous enuf. i can accept that the definition is flawed, but i can not accept that "134340 pluto" is a planet.\n\nthis was the right thing to do, believe me. this does not change anything about pluto or the solar system. this just corrects the mistake of classifying pluto as a planet initially.\n\nthis same thing happened has happened before. in 1800, an astronomer found a body orbiting the sun between the orbits of mars and jupiter and thought it was a planet. astronomers finally stopped classifying them as planets after they found several other bodies with similar orbits, and no one thinks ceres, pallas, juno, and vesta are planets today.\n\nmany astronomers consider pluto and charon to be a binary system, but two small bodies orbit that system. they are called nix and hydra.\n\nincidentally, "134340 pluto" was never a moon of neptune. neptune did capture triton. this is why triton has a retrograde orbit

First of all, it is not galaxy you are talking about, it is solar system. Secondly, a lot of people here are saying why ask such a stupid question. What most of them probably don't know is that while pluto is the smallest of our "officially classified" planets it has come to light in recent months that we may have more planets. \n\nThe debate has been raging on in the space exploration community that recently discovered bodies past pluto may actually be planets in our system as well. They are also saying they may take pluto off the official planet list because it is looking more and more like a captured asteroid compared to these new planets.\n\nFor those who want to read more about these new planets, do a search for the planet Xena (which is the temporary code name for the new planet). \n\nIn short, Pluto is "currently" the right answer but if it is removed from the list, then mercury will be the smallest planet.\n\nHope this helps!

If you weighed 150 pounds on Earth, your weight on Pluto would be just 10 pounds.\n\nBecause Pluto has so little mass compared to Earth, it has far less gravity. Pluto, the least massive planet in our solar system has a mass equivalent to approximately 1/500th of the mass of the Earth. Consequently, the gravity on Pluto is 8% of the gravity on Earth.\n\nBy the way, since a "day" on Pluto is equal to 6.39 Earth days, you'd be less than 1/6th as old on Pluto as you are now on Earth, you skinny little 10 pounder, you.

Honey,\n\nThis answer is a bit metaphysical and you might think its silly but you can read it for the fun of it !\n\nThe planets of the solar system can affect us in different ways.\nIn everyone's life there is a pattern of how they affect him or her and this pattern is quite different among people.\n\nFor instance from January till May, Neptune might enter your astrological chart, this planet might carry wealth but it might have another effect like hitting your elbows against obstacles. So within this time range you might experience your elbow hitting against different obstacles like the car door , doors in your residence etc. .\nThis chart depends on your place and time of birth.\n\nIn Vedic science it is called the Jyotish Chart. You can search in the internet to get more information ; searching the terms Jyotish and Chart .\n\nNow about your specific question I would have to say that in order to neutralize or at least weaken the negative strength of the planets affecting you, you will have to get near to a zone called the absolute field were everything is absolutely positive and their is no sign of relativity and negativity.\n\nTranscendental Meditation, Reiki, Real not virtual religious acts, etc. are all methods to weaken the negative effects and strengthen the positive effects of the aforementioned planets.\n\nYou can write to me if you need more information.\n\nHope the best for you darling.

hehe it seems as if ive answered this question a dozen times .. \n\nAstronomy is Somewhat different then Astrology, for example, both the moon and sun are seen as planets in Astrology, also Astrologers have tracked the effects of some asteroids aswell.\n\nso the loss of pluto as a planet has no significance on Astrology. its still in space revolving around the sun and its effects are still tracked.\n\nalso Scorpios ruling planets are mars and pluto. Mars used to be the only ruling planet of scorpio intill the discovery of pluto, which is rather recent in the practice of astrology. so currently there are  3 signs that are co ruled by two planets\n\nScorpio - Mars and Pluto\nPisces - Neptune and Jupiter\nAquarius - Uranus and Saturn

Neither. It's the mass of the planet itself. Everything that has mass projects a gravitational field. The more massive an object is, the bigger its gravitational "pull". This is why objects like the Sun can support several large planets, while Pluto (which has a moon about a third the size of it) gets pulled around by its moon.

Are you talking about a real planet or Nibiru (aka Planet X)?  Note how I differentiate between the two.\n\nIf you're talking about a real planet (which I hope you are) it will probably depend on whether we end up changing how we define "planet" to accommodate new bodies that are being found beyond the orbit of Pluto.  If Pluto loses its planet status or new bodies are found, it would of course change which body is designated the "tenth planet."\n\nRegarding the 12th of December 2012, you'd probably be better off if you stopped paying so much attention to the Mayan calendar.  I doubt very much that anything of particular consequence is going to happen on that day, despite what New Agers are spouting nowadays.

All orbits are elliptical (note that circles are subsets of ellipses.)  Exactly how Pluto go to be where it is (and where also includes its coordinates in a velocity space, in addition to xyz space) is not known.  One interesting thing about it is that it is in a resonance with Neptunes orbit, so that whenever it is close to Neptunes orbit, Neptune is on the other side of the sun. Neptune's mass can't perturb Pluto.  In other words, Pluto is in a special orbit that is stable. \n\nI doubt it had its origin as a moon of Neptune, or else it likely would have been flung into a very radical orbit by an encouter with that planet. More likely it is one of MANY objects that found itself orbiting in similar orbits; all the others have long ago been removed from the picture by Neptune encounters.
