It wasn't discovered that anything "never existed." Rather, a new definition of the word "planet," which never before had a proper definition, has determined that Pluto, which has been considered a planet since 1930, does not meet the criteria. Thus, Pluto, which used to be the ninth planet, is now a "dwarf planet," not counted among the remaining eight. But it is still out there, right where it was before it was even discovered. This happened once before. The largest asteroid, Ceres, was discovered two hundred years ago and considered a planet at first. It was "demoted" after astronomers discovered many similar objects in nearby orbits.

Not sure what you mean. Are you perhaps confusing an object existing with it being recognised as a planet? It still exists when it is stripped of its status, (Lord Archer was stripped of his title but he still exists!)
But assuming you mean disputed claims as to whether objects being claimed to exist really do exist ,,,
There was a belief that an extra-solar planet existed around Barnard's Star 5.96 light years away. But then scientists disputed the claim and the view is now that the inference fronm the observations was incorrect.
There are several such disputed extra-solar planet claims "yet to e confirmed"
Ceres when first discovered in early 1801 then promptly disappeared again (round the far side pf the Sun) and the discovery was doubted, but it emerged again and was no longer "lost".
We may perhaps be in the middle of something similar?
==
The first contrinutor is way out. Ceres is an asteroid lying between Mars and Jupiter and it has been known about since 1801
Xena is the Trans-Neptunian Object currently farthest away from the sun, but there are as many as 40 TNOs that are currently nearer to the Sun than Xena is but whose orbits go much further out than Xena does, Sedna can be ten times as far away from the Sun as Xena ever is when Sedna is at its aphelion for example,

You're either talking about the planet that astronomers felt should exist between Mars and Jupiter or you're talking about Planet X. I think you're talking about Planet X.
The missing planet between Mars and Jupiter was based on Bode's Law from the late 1700's. Bode's Law was a mathematical expression that described the spacing between the planets. The problem with his expression was that it predicted a planet between Mars and Jupiter. His law just described a pattern rather than provide any physical reason a planet should exist there (actually, the asteroid belt occurs right where the fifth planet should have been located).
Planet X was proposed as a way to explain perturbations in Neptune's orbit. Being based on physics and orbital mechanics, it had a lot more reason to be true than Bode's Law. In fact, it turned out to be true - Planet X was Uranus. Except Uranus didn't completely account for Neptune's perturbations, plus had unexplained perturbations, itself. Hence Lowell Percival figured there had to be another Planet X even further out. In fact, Planet X turned out to be Pluto. Except Pluto (even after the discovery of its large moon, Charon) wasn't large enough to account for the perturbations of the outer planets, so another Planet X had to exist even further out than Pluto.
The problem wasn't that Percival was a moron. Given the information on the planets that existed, his predictions made sense. It wasn't until we got a better measurement of the outer planets' masses from the Pioneer 10, Pioneer 11, and Voyagers 1 and 2 missions that Percival's Planet X was proven to be non-existant (or at least not the large planet Percival expected).

Many astronomers conclude that Pluto has been improperly classified all along.
It is not a planet, they say, but rather a Kuiper Belt Object, a member of a swarm of comet-like objects beyond Neptune.
Clyde Tombaugh found Pluto on the afternoon of Feb. 18, 1930,
at Lowell Observatory

To find a planet that had never existed before ,would imply that planets self create themselve. And the story sells itself.
As far as morons are concerned some exceed the IQ of some geniuses. and some geniuses exceed the stupidity of some more ons.
What else can I tell you?

The temporary name for the "new planet" is 2003UB313 or UB313 for short.
UB313 was discovered by astronomers Mike Brown (Caltech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale University). One would assume that astronomers at Caltech, Yale University and the Gemini Observatory are hardly morons...
Please refer to the link below for more information on this planet.

2003 UB313. It's nicknamed Xena. It will the largest object in the new classe of "dwarf planet" Researcher Mike Brown discovered it.

Michael Brown of the California Institute of Technology in Pasadena found that new non-planet. It was nicknamed Xena, after that lame UPN show about an amazon warrior woman.
