Anyone know about the phantom planet that's the positive earth with an exact duplicate of us?

Interesting theory, it's called a doppleganger, and is supposed to be in our exact orbit, just on the other side of the sun so we can never see it.

Fascinating subject:  On the balance of probabilities, if the universe is infinite, someone identical with you, typed the same question, on an identical computer, on an identical forum and is being answered by someone identical with me.    Mind blowing if you think about it.........

Simple way to look at this perinnial question. One solar system. One planet like earth froms. Sustains life. Universe is filled with billions of stars. Some the size of our Sun. Some have planets revolving round them. Like earth too. Take a wild guess and u wont be wrong. \n;-)

They say that everyone has a twin somewhere in the world.\n\nThen again they also say that no two fingerprints or snowflakes are exactly the same, so by that logic, I think that we all have someone else on this planet that looks almost identical to us, but noone is exactly like us.

No.  \nHere is why: Although the list of known extra-solar planets is growing, to my knowledge, none have been described where there are two in the same orbit.  In terms of solar planets (ie us) although it is true that two planets in our solar system cross orbits, this is not 'sharing' the same orbit (at least in the sense of your question I think).  It seems possible enough, but has not yet been described.

If anyone had seen one and been able to prove it without a doubt, you wouldn't need to ask the question because it would have been all over the news.  Unless the government covered it up, that is...  I think the government is likely to cover something like that up if it found out (and could cover it up) because of the likelihood of a mass panic.\n\nHowever, beyond a doubt there are other planets in the universe.  Astronomers have worked out their existence with high-powered telescopes.  And that -was- on the news a few years ago.  So hey, ya never know.

What you are asking is essentially, are the other planets in the same plane as the earth's orbit, known as the ecliptic? No, they are not, but they are pretty close. The angle between their orbits and the plane of the ecliptic is called the inclination:\n\nMercury     7°\nVenus      3.39°\nEarth  0°\nMars      1.85°\nJupiter1.3°\nSaturn2.49°\nUranus0.77°\nNeptune1.77°\nPluto      17.2°\n\nAs can be seen from this list, most of the planets have orbits in the same plane as the earth, more or less. \n\nIt is also interesting that all of these planets orbit in the same direction, in more or less the same plane, and also spin in more or less the same direction (counter clockwise when seen from the celestial north pole, looking down on the solar system). The only two planets which have their rotional axes different are Neptune (tilted on its side) and Venus (a retrograde rotation; that is, it is rotating clockwise when seen from the celestial north pole). These spins also agree with the spin of the sun, which has a huge amount of mass and therefore angular momentum by comparison. It is thought that these spins are all so similar because the solar system formed out of one big rotating ball of material that coaelesced into the orbiting, spinning planets and the spinning sun.

no the fourth planet from the sun.put me on best answer please!\n\nHappy Trails ♥!

I just picked this information up off a website... I found it using "Google"\nSEDNA: \nthe tenth planet in our solar system?\n\n \n Sedna, which was very recently discovered at the outer limits of our solar system, seems hardly any different from Pluto. It is a massive, spherical body that revolves around the Sun and may even have its own satellite. But does this really mean that Sedna is a planet?

Never heard about it. There are many places in the web \n\nhttp://astronomylinks.com/solar_system/planets/\nhttp://www.absoluteastronomy.com/\nhttp://curious.astro.cornell.edu/planets.php

There could be another planet ... but it will be so far away from the Sun that it may be even more difficult to find than Xena (the 10th planet).\n\nAs to the solar system existing in another planet?  Hmmm .... seriously mate ... no.  Not a chance.

didnt you just freaking ask this question like 5 minutes ago??? you can see the same planets in any location, as long as it is dark enough, due to their distance from earth.

Actually, you're all wrong.  It's 2003 UB313 the recently discovered 10th planet which has not yet been given a perminent name.  As of July, 2005, the planet 2003 UB313 was approximately 97 AU from the sun, over twice the distance between the sun and Pluto (40 AU).\n\nIf you're actually wondering about the 2nd farthes planet (which may be the case as most people don't know about 2003 UB313), most of the time (including the present) it's Pluto, but Pluto has a crazy eliptical orbit (one of the reasons its status as a planet is debatable), and sometimes crosses paths with Neptune.  When I learned the order of the planets in 2nd grade, Neptune was farther away than Pluto, so instead of "my very educated mother just served us nine pizzas," we learned "my very educated mother just served us pistachio nuts."

It is a theoretical planet. There have been numerous reports of finding it. It is most likely the same kind of thing as Pluto, which is an asteroid that gets lightly caught in the suns gravity. They are actually starting to think there are a lot of little asteroids that are "mini-planets" like that out past Pluto.
