What is the name of the planet, discovered relatively recently, beyond Pluto?
Answers:
No new planets have been discovered beyond Pluto. Now even Pluto is officially not considered a planet anymore. It was demoted.
A few Kuiper belt objects have been discovered recently though. Being "2003 UB313" the largest one so far.
There are two that werer discovered in 2003. They are called Xena and Sedna, though they are not "officially" considered planets.
for details on Xena, look here:

for details on Sedna, look here:

"Xena" is its nick name.
Not sure what they're going to actually name it
There was one that was only a number. Don't remember the number, but it didn't have a name. At least then.
XENA
There are 2 planetoids beyond Pluto, Charon and Xena.
that wasnt a planet they sed they found LIGHT beyond pluto
The planet beyond Pluto is officially classed as a "Dwarf Planet" along with ceres (in between mars and jupiter), Pluto, and the planet you wish to know about UB313 nicknamed "Xena"
To conclude, the planet is called UB313
EDIT: Above i noticed that someone said Charon, in actual fact Charon is a moon of pluto however it is rather large compared to Pluto and sometimes considered to be "twins" since charon does not spin on its axis as it orbits.
The temporary designation of the dwarf planet discovered that is bigger than pluto is 200 UB 313. Its nickname is "Xena" and it's moon's nickname is "Gabrielle".
