There has over been speculation as to the existence of Planet X.Im not talking about planetoids(pluto sized).I am talking about a planet well the size of Neptune,Possibly bigger.

Ever since the discovery of Neptune,scientists and astronomers had long wondered why the outer giant planets had "wobbly" rotations and unstable orbits.The answer many astronomers came up with was another planet either the same size as neptune or bigger way beyond Neptune.This began a global search and for decades many astronomers worked day and night trying to find this planet.By the 1930`s pluto was discovered along with its moon(1970`s).Also pluto only measured an estimated 3,000km in diameter compared to Neptunes/Uranus`s 50,000/60,000km in diameter.Further more,additional planets have been found recently but only being slightly larger,and some smaller than that of Pluto itself.

My question is,how many of believe here is a planet of significant size out there that might be causing these gravitation disturbences in Neptune and Uranus?

Object Bigger than Pluto Discovered, Called 10th Planet

29 July 2005

Astronomers have discovered an object in our solar system that is larger than Pluto. They are calling it the 10th planet, but already that claim is contested.

The new world's size is not at issue. But the very definition of planethood is.

It is the first time an object so big has been found in our solar system since the discovery of Pluto 75 years ago.


Old news.

I am not talking about planet "Zena" discovered by a kiwi astronomer afew months ago.This planet measured at 3800 km in diameter.Im talking about a planet well within a size of 50,000 km in diameter or more.A planet large enough to cause gravitation disturbences in those of Neptune and Uranus.

There definately could be a planet the size of Neptune past Pluto because of the "wobbly" rotation and unstable orbit of Neptune. The thing is, I thought that they are able to determine where it would be in the sky just by the gravitational pull on Neptune.

Actually, I just did a little more searching on this and it appears that this was speculation years ago but has pretty much been proven false thanks to modern measurements.

The Rise and Fall of Planet X

As Slink rightly says, modern measurements, using data provided by Voyager, show that in fact there are no perturbations to Neptune or Uranus' orbits and thus no reason for supposing the existence of another large planet beyond Neptune. Though probably there are many more Plutos, Quaoars, Sednas, and 'Xena's out there still to be found...

Not to mention, unless it was a dark matter planetoid that reflected no light what so ever, it would be a little hard to hide. And even a big blob of dark matter would mask background stars and be rapidly detected.
