You might be referring to the dwarf planet Eris.
It was originally photographed in 2003, and discovered in 2005. It is located just beyond the Kuiper Belt, and when measured by the Hubble Telescope, turned out to be slightly larger than Pluto. It is therefore the ninth largest body orbiting our sun.
The discoverers of Eris actually labelled it the 10th planet, but after the term "planet" was redefined last year Eris, Pluto and Ceres were reclassified as "dwarf planets"
Eris has at least one moon which is known as Dysnomia

Originally Planet X was the planet assumed to be beyond Pluto which would make it the 10th planet (X is the Roman numeral for 10, and its also used as an unknown quantity in a math problem).
So it was a good term, but it turned out that the planet didn't exist (and as far as we know right now it doesn't exist).

Planet X was come up with as the name of a planet that was outside the orbit of Neptune, supposedly it was "detected" by the effects it ha on the orbits of the other planets.
After many years of looking Clyde W. Tombaugh found a planet out in the distance - it was Pluto. Unfortunately it could not have caused significant disturbances in other planets orbits as its mass was so small
Some people still believe there is a "Planet X" out there

I've heard awhile ago they thought they had found another planet out past Pluto. I haven't really heard anything more lately but since they don't consider Pluto a planet anymore maybe they will change its name to Planet IX, who knows.

I don't know what you've heard about planet X, but this is how astronomers often refer to an hypothetical planet -- that is, where there are conditions in outer space that suggest a planet is causing them (such as unexplained gravitational fields) but where no one has identified such a planet. That doesn't mean it doesn't exist, it just means no one has yet discovered it.Is that what you're asking about, or is this some Sci-fi quiz?

Yes, probably everything u've heard is true. They have recently found a planet beyond Pluto that is larger than Pluto itself. Here's some more info.
